Ukraine's President has called on Australia to provide more military support to keep his country's forces armed to continue the fight against Russia's invasion.

Volodymyr Zelenskyy made a powerful address to a joint sitting of Australian Parliament today.

The essence of his address was to hold Russia to account due to the threat the country poses to global security.

Mr Zelenskyy emphasised Ukraine can push back against Russia's attack, however, military and humanitarian assistance from Australia — particularly armoured vehicles — and other countries is urgently needed.

"If we can count on the support of the free world, on your support, on your assistance," he said.

"We need it not just in a couple of months, we need it urgently now."

He claimed Ukraine's "dream is undefeatable" if it can count on the global community's support.

Australia pledges additional $25 million in support

Mr Zelenskyy's address came after Prime Minister Scott Morrison pledged a further $25 million of defensive military assistance to the Ukrainian Armed Forces.

This funding will go towards "tactical decoys, unmanned aerial and unmanned ground systems, rations and medical supplies".

It brings the total in assistance to Ukraine to $116 million.

Mr Zelenskyy thanked Australia for the ongoing support but continuously emphasised throughout his address for more sanctions against Russia and to essentially cut off the country.

"We can and should do more, we need more sanctions against Russia until they stop blackmailing other countries with their nuclear missiles… no Russian vessels should be allowed in international ports," he said.

"We have to stop any business activity with Russia… we have to stop any intention of Russia to bypass the sanctions… We have to keep those who are fighting against this email armed."

'Unpunished evil comes back'

Mr Zelenskyy spoke of the MH17 tragedy in 2014 where a passenger flight was shot down while flying over eastern Ukraine, allegedly by Russian forces.

He said Russia has never been held accountable for this.

"Did we manage to hold those accountable who caused the tragedy? No, they are hiding in Russia," he said.

"The unpunished evil comes back, and I would say… with inspiration. With the feeling of all-mightiness.

"If we punished Russia in 2014 for what they did… there would be no invasion."

Russian threat of nuclear war

Mr Zelenskyy touched on the threat of nuclear war and claims Russian officials are threatening to use nuclear weapons on those who do not submit to the country's demands.

"It has become a real threat to your country and people as well," he said.

"The country which is using nuclear blackmailing should receive the sanctions that would show such blackmailing is destructive for the blackmailer itself."

Wet weather has triggered a landslide in south-east Queensland, with clean up crews working to restore access to roads.

Commutes through Springbrook Road on the Gold Coast were interrupted this morning when part of the cliff above gave way, covering the road in rock and rubble.

The road was immediately closed with work expected to take days to remove the debris.

Springbrook recorded 352mm of rain in a week.

Further west, Beechmont Road remains closed after another landslide caused even more damage after it gave way this week.

A 35-minute detour has been established for locals needing to access their homes.

In Dalby, west of Brisbane, several roads remain closed due to flooding.

On the Gold Coast, a major clean-up is underway, including to clear debris from beaches and roads.

Southport resident Carol Murphy said she became stranded in her apartment after floodwaters inundated her carpark for the second time in a month.

Ms Murphy said the smell of sewage was lingering after covering the ground with waste and toilet paper.

"Go in the hallway where I live, you can still smell it coming up," she said.

"Basically I was stranded, couldn't get to my car, wasn't going to attempt it."

Across the border, the main street of Byron Bay remains underwater.

Flooding remains at a major level in Lismore, devastating residents still recovering from February's flood disaster.

Ambulance Victoria has admitted it needs to "get better" as it sits on the cusp of a complete cultural overhaul.

Victoria's Equal Opportunity and Human Rights Commission handed down its final report into the organisation on Thursday, calling out systemic problems that facilitated bullying, sexual harassment and discrimination for decades.

In part, it read: "The Board and Executive Committee did not fully anticipate, recognise, analyse, prioritise or systematically address the unlawful conduct and harm identified by this review."

Commissioner Ro Allen added the issues are spread "right across Ambulance Victoria."

"Those things that have been included to help women haven't worked. They're not good enough."

Almost half (47.2 per cent) of the more than 2000 paramedics surveyed for the report experienced discrimination and more than half (52.4 per cent) had been bullied.

Testimony in today's 800-page document included comments from interviews calling out a "boys club" in which "women are usually overlooked" for promotions.

One employee labelled the system "notoriously corrupt".

Chief executive of operations Libby Murphy, who worked through a similar review during her 35 years with Victoria Police, said "we need equality, we need diversity".

"I think that's a reflection, it's not an excuse, but it's a reflection of society and what we need to change."

"If we get this right, the community is better served."

The report did not call to sack Ambulance Victoria's board or executives, but the organisation's head of people and culture resigned this week, days before the final report was made public.

Danny Hill, Secretary of the Victorian Ambulance Union, said a resignation "doesn't fix the problem".

"We need people feeling welcome at work and feeling safe at work and if we don't, yes, we do have an impact to the service provided," he said.

Paramedics have been at the centre of a health crisis gripping the state.

They're the faces we see "ramped" outside Victorian hospitals, waiting with patients needing care from a workforce that was missing 1906 staff to COVID isolation today.

They're also the faces up to a dozen Victorians were desperate to see as they died, waiting for a Triple Zero call to be answered between October and January.

Brad Battin, Victoria's Shadow Minister for Emergency Services, said Premier Daniel Andrews is accountable.

"The blood is on your hands. You can fix it, you should have fixed it, you failed to fix it," he said.

"More people will die here in the state if they don't get this right."

The premier announced $115 million for the state's ailing ESTA call taking service in March, after 60 Minutes broadcast recordings of Triple Zero calls that were left on hold for 15 minutes as Victorians were dying.

"We will continue to resource this service to make sure it's as good as it possibly can be," Minister for Employment Jaala Pulford insisted today.

A malicious software command that immediately crippled tens of thousands of modems across Europe anchored the cyber attack on a satellite network used by Ukraine's government and military just as Russia invaded, the satellite owner disclosed today.

The owner, US-based Viasat, issued a statement providing details for the first time of how the most serious known cyberattack of the Russia-Ukraine war unfolded.

The wide-ranging attack affected users from Poland to France, getting quick notice by knocking off remote access to thousands of wind turbines in central Europe.

Viasat would not say who it believed was responsible for the attack when asked separately by The Associated Press.

Ukrainian officials blame Russian hackers.

The Viasat attack, coming just as Russia was launching its invasion, was considered at the time by many a harbinger of serious cyberattacks that could extend beyond Ukraine.

Such attacks haven't yet materialised, though security researchers say the most impactful war-related cyber operations are likely occurring in the shadows, focused on intelligence-gathering.

A free-for-all of lesser attacks, many apparently carried out by volunteers, have been launched against both Russia and Ukraine.

A persistent drumbeat of malicious hacking that Ukrainian officials and cybersecurity researchers blame on Russia-affiliated attackers has plagued Ukraine throughout the more than month-long conflict.

One of the most serious hacks largely knocked offline the internet and cellular service of a major telecommunications company that serves the military, Ukrtelecom, for most of Monday.

Today, Google said it had identified a state-backed Russian hacking group engaged in a credential-phishing campaign targeting the militaries of multiple Eastern European countries and a NATO think tank.

It said it did not know if any of the targets were successfully compromised.

The attack on the KA-SAT satellite network highlighted how vulnerable commercial satellite networks that serve both military and non-military clients can be, with the impact felt by individuals and businesses far from the battlefield.

It began in the early hours of February 24 with a distributed denial-of-service onslaught that knocked a large number of modems offline.

A destructive attack followed in which a malicious software command sent across the network rendered tens of thousands of modems across Europe inoperable by overwriting key data in their internal memory, Viasat said.

"We believe the purpose of the attack was to interrupt service," it said.

It said it has shipped 30,000 replacement modems to affected customers across Europe, most of whom use the service for residential broadband internet access.

The attack caused a major loss in communications in Ukraine in the early hours of Russia's invasion, top Ukrainian cybersecurity official Victor Zhora told reporters earlier this month.

Asked by the AP last week who was responsible, Mr Zhora said, "We don't need to attribute it since we have obvious evidence that it was organised by Russian hackers to disrupt connection between customers that use this satellite system."

He said he did not have information on whether the service had been restored and could not say which Ukrainian agencies beyond the military were affected.

Contracts show, however, that Mr Zhora's own agency, the State Service for Special Communications, is among customers that also include police agencies and municipalities.

Viasat said "several thousand customers" located in Ukraine were impacted.

Viasat, based in Carlsbad, California, said the initial denial of service attack had emanated from modems inside Ukraine.

It did not specify how the destructive malware entered the network other than to say a "misconfiguration" in a virtual private network appliance was compromised, allowing the attackers to gain remote access from the internet to a "trusted" management console used to administer the satellite network.

From there, the attackers were able to simultaneously send the disabling command to modems across Europe, rendering them useless but not permanently unusable, Viasat said.

It was not known how the attackers breached the VPN appliance. 

Satellite cybersecurity researcher Ruben Santamarta said it was important to know whether they had obtained credentials or exploited a known vulnerability.

Viasat declined to provide specifics Wednesday, citing an ongoing investigation.

Gregory Falco, a Johns Hopkins University professor specializing in satellite system security, said the impact on affected systems was minor compared to what the attackers were capable of doing.

Mr Falco said it's likely they've maintained a foothold.

"The attackers don't want to show their whole hand or any of their positioning for how they plan to persist in the network," he said.

The hacked ground-based network is run by Skylogic, an Italy-based subsidiary of Eutelsat, from which Viasat purchased the KA-SAT satellite in April of last year.

Viasat's investigation of the attack was done by the US cybersecurity firm Mandiant.
