A social media scam targeting travellers looking for customer service support has prompted a warning from an international airline.

Low-cost carrier AirAsia today warned customers to remain vigilant against customer service scams after online posts listing fake AirAsia customer service numbers circulated on social media.

Several Fake X and Instagram accounts using AirAsia's logo and posing as customer service pages were flagged by the Malaysian-based airline as unofficial accounts.

"Just to clarify, those numbers are not affiliated with AirAsia," AirAsia Deputy Group Chief Operating Officer Kesavan Sivanandam said.

AirAsia's customer support services are operated exclusively through digital platform AskBo and the carrier does not offer customer service via phone calls.

"If you need help with your booking, flight changes or travel information, the safest way is through AskBo on the AirAsia MOVE app or airasia.com," Sivanandam said.

"And always be careful about sharing your booking information, personal data, payment details with unverified sources."

Customers were advised to verify information through "official AirAsia channels" such as the airline's website and verified social media accounts to avoid being scammed.

"The airline continues to monitor the circulation of misleading information and reminds the public to remain vigilant against potential fraud, especially during the busy festive season travel period," AirAsia said in a statement.

Community activist says people need support after a man tried to siphon petrol near a gym.

The ceremony to bestow Luxon with a chiefly title has dogged the PM’s Samoa visit.

Police attended after reports of ‘unlawful activity’.

Australian mortgage holders will have to stretch their budgets further following a decision by the Reserve Bank of Australia (RBA) to hike interest rates for the second time in a row.

Today's hike brings the official cash rate target back up to 4.10 per cent after the RBA handed down a 25-basis-point increase February, which took the cash rate up to 3.85 per cent.

Rate tracking by Canstar found after the last hike, the vast majority of lenders passed on the hike in full within two weeks of the announcement.

So what will this mean for mortgage holders?

Mortgage holders with a debt of $500,000 could pay at least $151 more per month with the cumulative increase from February and March, according to data from Canstar.

For someone with a $600,000 mortgage, the total increase between February and March would be $181 a month.

Those with a $700,000 mortgage are expected to pay more than $211 a month after the two hikes.

For someone with $800,000 left on their mortgage, the two hikes could add an additional $241 to their monthly repayments.

For those with a debt of $900,000, the culmulative increase could be an extra $271 per month.

Mortgage holders with $1 million of outstanding debt are likely to pay an additional $301 extra a month.

Canstar data insights director Sally Tindall said while the banks were likely to pass the rise through to their variable rate customers in full, there were ways to outsmart the rise.

"Banks might apply a blanket increase to their variable customer base, but still be willing to hand out cuts on a case-by-case basis," Tindall said.

"Often it's just a matter of stating your case."

A stolen white Ford Ranger was stopped at Karangahape Rd and four people were arrested.

Digital birth certificates are now available in NSW, but only for the state's hundreds of thousands of young people.

From today, people aged 16 to 21 who hold a photo card or driver's licence can choose to set up a digital birth certificate for free on the Service NSW app.

The state government said the digital document was secure and designed to adhere to international security standards.

"I'm proud that NSW is the first place in Australia where young people across the state can carry their birth certificate securely on their phone, instead of having to rummage through drawers or call mum and dad," Digital Government Minister Jihad Dib said.

"For young people living away from home for work and study, this digital document provides instant convenience when they need their birth certificate to apply for certifications and licences – making it easier to apply for jobs.

"The digital birth certificate offers a secure and convenient way to access one of the most important identity documents, giving people greater control over personal information.

"It's the same as having a birth certificate in your pocket, but much more secure."

Digital birth certificates can be used to verify identities and apply for licences or certificates, such as the Responsible Service of Alcohol.

The state government said the new digital tool could be used for more services over time. 

Service NSW and the NSW Registry of Births, Deaths and Marriages are working with businesses and the community to make it easier to use the digital birth certificates. 

It's not clear when the government will roll out this service to other demographics.

The service is free, compared to ordering a physical birth certificate, which costs $68 or $101 for priority services.
