Tenacious D's Kyle Gass says he's "hashed it out" with Jack Black after his controversial comment about an assassination attempt on US President Donald Trump forced the cancellation of their Australian tour and threatened the band's future.

In a Rolling Stone interview that delved deep into the ferocious global backlash to his ill-judged quip onstage in Sydney last year, the guitarist joked the band's return would be "bigger than Oasis" and labelled an Australian senator a "grandstander" over calls for them to be deported.

Gass said he'd been having "the greatest day ever" when the duo behind the ARIA platinum-selling single Tribute took to the stage for their second show at the ICC Sydney on his birthday in July last year.

But then he uttered the "five one-syllable words that brought down the empire".

Presented with a cake and asked by Black to make a wish, Gass joked, "Don't miss Trump next time."

It was the same day Thomas Matthew Crooks left Trump bleeding from the ear with an assassination attempt at a rally in Butler, Pennsylvania.

"I'm human, I made a mistake. I was going for a joke. But timing is everything. If there was ever a 'too soon', it was this," Gass told the magazine.

It wasn't until the band were "partying in my hotel room" after the show that they started to see reports of his comments and Gass realised what was coming.

"It's overwhelming. It's like a tsunami of shit rolling over you. And then there's the regret. Like, 'Why would I do that?' I just didn't put it together. And the ramifications were so huge," he said.

Gass said there were even "safety concerns" and someone called his "poor 95-year-old mum".

Black cancelled the tour and put "all future creative plans … on hold" as those involved went into damage control, sparking criticism from some corners that the movie star had thrown his decades-long friend under the bus to protect his Hollywood career.

Gass said it didn't really surprise him.

"I might have deserved it," he told Rolling Stone in an interview published on Wednesday.

"Or, he had to protect himself from his loose-cannon partner over here. I totally understood once safety concerns got in.

"I might have tried to finish the tour, and I think sometimes these things can blow over, but at the time, it's hard when the tsunami of shit is coming at you."

Gass said it was "hard" but he and Black later "hashed it out".

"Jack and I are all good. At the end of the day, we're friends. I've known Jack since he was 18, and it's been such a long marriage, really.

"You go up and down, and we've always taken long breaks. He's had a lot of stuff to do, and I've got my other projects. So it doesn't even feel that different now."

The 65-year-old, whose Kyle Gass Band project has a new live album coming out, also had a parting shot for United Australia Party senator Ralph Babet who called on then-Immigration Minister Andrew Giles to deport the duo.

"It didn't take long to be like, 'Oh, this guy is such a grandstander'," Gass told Rolling Stone.

"We're so used to it over here, where people take the opportunity to make a grand statement. And then the next day, my agent dropped me. And I was like, 'Well, gee, it would have been nice to at least talk to you or something'.

"But I think he wanted to get in the news cycle too … It did feel like an overreaction. But that speaks more to my relationship with my agent."

Black last August said the band would "be back when it feels right" and Gass was even more enthusiastic this week.

"We're gonna come back — it's gonna be bigger than Oasis!" he said.

Silence has fallen across Australia in a powerful moment of mourning for the victims of the Bondi terror attack and a show of solidarity with the Jewish community.

A national day of mourning culminates tonight with a service at the Sydney Opera House, echoed with light at 14 other buildings around the country.

Light Will Win – A Gathering of Unity and Remembrance was set to include the lighting of 15 candles to remember those slain at the Hanukkah by the Sea festival on December 14 and addresses by members of the Jewish community and political leaders.

The Sydney Opera House was flooded in white light to honour the victims after the national flag flew at half-mast at all federal government and NSW government buildings out of respect for the grief over the 15 people killed in the attack.

Constable Scott Dyson and probationary Constable Jack Hibbert made their first public appearance after being injured responding to the attack.

Bondi hero Ahmed Al Ahmed and NSW Police Assistant Commissioner Peter McKenna joined representatives from each of the families who lost loved ones to light a candle on stage.

Another 14 buildings around the country, including the Bondi Pavilion, will also be lit up in white light to honour the victims.

The theme of today, chosen by the Chabad Community in Bondi, whose Hanukkah event was targeted in the attack, is "Light will win, a gathering of unity and remembrance".

Chabad NSW head Rabbi Pinchus Feldman called on those listening to recognise the dignity of every human behind and find strength in Noah's seven laws that underpin Judaism.

"In deep mourning, yet with a steadfast spirit, we pray for the triumph of light over darkness," he said.

"As the prophet Isaiah,proclaimed, the people who walked in darkness have seen a great light.

"May he who makes peace in the heavens, the almighty God, bring peace to Australia, to Israel and to all of humanity."

Four sons who lost their fathers in the attack — Nossen Schlanger, son of Rabbi Eli Schlanger; Shlomo Levitan, son of Reb Yaakov Levitan; Yaakov Tetleroyd, son of Boris Tetleroyd; Tzvi Kleytman, son of Alex Kleytman; and Zev Weitzen, son of Tibor Weitzen — recited the Mourner's Kaddish.

Throughout the evening, more than a dozen moving tribute videos were played, sharing intimate and touching details of the lives lived before they were cruelly snatched away on December 14.

Ya'akov Tetleroyd, still lying in his hospital bed, remembered his father, Boris, a smiling man who everybody loved, the man who taught him to ride a bike and who would randomly burst into song.

"I was always just amazed how he was able to fix everything," Ya'akov said.

"Whatever was going on in my life. He was able to find a solution for it."

Speaking earlier today, Prime Minister Anthony Albanese said the Bondi Beach terror attack remained "a stain on our nation".

"Today is an opportunity for us to remember and pay respect to the 15 lives," Albanese said.

"A chance for us to, if we have faith, to pray. If we don't, to hope that those who still suffer from injuries and are recovering, both physical and mental, have the opportunity to do so."

He said today was a chance for the country to "wrap our arms" around the local Jewish community.

"Today, we share their grief. A grief with no ending, only a beginning," he said.

National institutions in Canberra and in NSW were illuminated as a symbol of light this evening, a commemorative installation, 15 Pillars of Light, was in place in Canberra and around the country.

"The pillars will be lit up in locations around the country and will serve as a visible symbol of mourning, remembrance, and national unity," Albanese said.

Throughout the day, candles were handed out in Martin Place to be lit tonight in windows across Sydney. 

"I think it's an opportunity to reflect on the victims, but also the contribution they made to our country," NSW Premier Chris Minns said.

The premier visited a Jewish Care centre in Woollahra, meeting with Rabbi Mendel Kastel and his son, who witnessed the entire attack.

"He was actually there. It was a very difficult time," Rabbi Mendel Kastel said.

"For a little while, we couldn't find him."

Throughout the day, the shared sentiment was that this must be a turning point.

"We need to remember those who've lost their lives and may their memories be a blessing," NSW Opposition Leader Kellie Sloane said. 

"The bigger mountain to climb is making sure this never, ever happens again."

St Paul's Anglican Cathedral in Melbourne marked the day with a multi-faith vigil.

Flags across Adelaide flew at half-mast across the city.

In Perth, a service at St George's Cathedral offered prayers for the fallen, while this afternoon at St Mary's in Sydney, a special mass acknowledged the 15 souls lost in December.

All Australians are encouraged to observe a minute's silence at 7.01pm AEDT, and to leave a lit candle in their window or on their doorstep in solidarity with the Jewish community.

Albanese said this morning radio and television broadcasters would also hopefully hold that minute's silence.

"We live in very difficult times, that is the truth," Albanese said.

"And in a time of turbulence, I really want this nation to be a light for the world. We have an opportunity to do that."

Social Services Minister Tanya Plibersek told Today people were also urged to perform a "mitzvah", an "act of goodness and kindness" for other Australians.

"These acts can be as simple as checking in on a neighbour, volunteering time, offering support to local businesses, or donating to those in need," Albanese said earlier this week.

An invitation-only memorial event, organised by Chabad of Bondi, is live-streamed from 7pm AEDT on the organisation's YouTube channel.

The Jewish community will also gather at the Sydney Opera House, which will be lit up in white in a gesture of solidarity and mourning.

"I'm very thankful the NSW government for giving us this opportunity to reclaim it, not just for us as a Jewish community, but obviously for the whole Australia and globally," Rabbi Mendy Ulman said.

A "dome of heat" set to loom over south-eastern parts of Australia over the next week has fire authorities on alert, as Victorian bushfires that started almost two weeks ago continue to burn.

A sweltering trough travelling from Western Australia is expected to hit Adelaide and Melbourne on Saturday, where the mercury is set to surge to 42 and 40 degrees respectively.

Authorities in Victoria are warning the mercury could remain above 40 degrees in northern parts of the state for up to a week.

"Currently a dome of heat is expected to sit over Victoria, not just this weekend, but persisting well into next week," Bureau of Meteorology's Kevin Parkyn said.

Mildura is forecast to hit 43 degrees on Saturday, with an extreme fire danger rating for the Wimmera and South West Districts.

A cool south-westerly wind change will bring a reprieve for the south-west of the state, including Melbourne, on Saturday evening, but the heat is expected to stick around in northern parts.

The mercury will be somewhat cooler on the south-west coast on Sunday and Monday, before potentially record-breaking heat returns to the state on Tuesday.

Melbourne is tipped to reach 41 degrees on Tuesday as the trough travels further east, with a top of 43 possible in the suburbs.

The heat will be even more intense up north, with 47 degrees forecast for Mildura, 45 degrees in Bendigo and potentially 48 degrees in Ouyen.

"Many centres are probably going to break their all-time maximum records," Parkyn said.

Another cool change should begin to bring relief to south-west Victoria by Tuesday afternoon.

Authorities are urging Victorians to be aware of their environment over the long-weekend and to limit the use of campfires.

"We do want people out there in Victoria spending money in regional Victoria, enjoying themselves, but we've got a lot of really severe and dangerous weather ahead of us and we just ask that people take care and act responsibly," Fire Forest Management Victoria Chief Fire Officer Chris Hardman said.

"If you are camping, with the temperatures we're seeing coming our way, do you really need a campfire at all?"

South Australians are also set to swelter through the heatwave across the week.

The mercury is expected to peak at 42 degrees in Adelaide on Saturday, before dipping slightly to 36 on Sunday and again rising to 43 degrees on Monday.

'Risk of fire will return'

Fire authorities are warning the heatwave is expected to agitate bushfires still raging across Victoria.

The Wimmera and South West districts will be under an extreme fire danger rating on Saturday, while most other parts of the state will have a high rating.

Hot, dry conditions will persist overnight on Sautrday and could exacerbate fire danger, the Bureau of Meteorology warned.

Blazes in Walwa, Wonnangatta and Mallacoota remain uncontrolled and four others are also still burning.

More than 1500 structures have now been declared damaged or destroyed by fire and a state of disaster remains in place across Victoria.

The largest and most destructive blaze at Longwood was marked as contained at 5pm last night, meaning the fire continues to burn, but its spread has stopped.

The Longwood fire has burned through 144,000 hectares and destroyed 320 homes, with dozens more damaged and nearly 900 outbuildings impacted.

While wind speeds over the week aren't expected to be as high as the strong gusts on January 9, authorities are asking Victorians to remain vigilant.

"The risk of fire will return," CFA chief officer Jason Heffernan warned.

"We will be declaring total fire bans throughout the course of this fire event."

Parkyn warned a dry outlook could make it even more difficult to quash the fires, and any new ones that start.

"We're not expecting any significant rainfall to affect Victoria over the next two weeks," he said.

Almost two dozen firefighters have been called in from New Zealand to help bolster efforts.

They will be joined by 74 Canadian firefighters expected to arrive in Victoria early next week.

The ‘shaken’ victim was left with serious injuries after the attack.

“I’m truly blessed to have been raised by a dad like him,” says Peter Walker’s daughter.
