My guess,....just guess
If you are staying in Australia, then you will be an Australian tax residence. Then bnm will tell their Australia counter part thru their information exchange agreement abt your bank a/c information in malaysia.

Australian resident
As an Australian resident for tax purposes, you must declare income you earn anywhere in the world on your Australian tax return. This is known as your worldwide income. This includes any foreign income you may receive from:

pensions and annuities
business activities
employment and personal services
assets and investments
capital gains on overseas assets.
Australian residents (for tax purposes) with a tax file number generally pay a lower rate of tax than foreign residents.

Australian income tax rates for 2020–21 and 2021–22 (residents)
Income thresholds Rate Tax payable on this income
$0 – $18,200 0% Nil
$18,201 – $45,000 19% 19c for each $1 over $18,200
$45,001 – $120,000 32.5% $5,092 plus 32.5c for each $1 over $45,000
$120,001 – $180,000 37% $29,467 plus 37c for each $1 over $120,000

So that means, you will pay to Australian govt and nothing to do Malaysian govt unless that money in malaysia are used as an income generating platform in malaysia like property gain tax for example?

But if you are not a malaysia tax residence, how to go around that?

You will then become a Malaysian tax residence👍👍
But, Then as per post 216,
Australian residents (for tax purposes) with a tax file number generally pay a lower rate of tax than foreign residents.

Will you continued to be an Australia tax residence too?

I dont mind paying Australian taxes if I can make Aussie dollar n still hv enough to Aussie dollar to save.

foreign source income implies you're local tax resident/payer with foreign income... if you're now a foreign tax resident with foreign income, this law probably doesn't apply to you...

but you can't simply stay >180day somewhere and declare you're not a local tax resident anymore... need to clear tax with irb and tell them sayonara...

and now any income in malaysia (e.g., rent out your old house, etc), you supposed to pay a flat-rate non-resident malaysian tax...and also top-up foreign source income tax to you australian tax...

World Bank says Malaysia ‘has plenty of scope’ to tax capital gains or inheritance, even as politicians say the contrary....

i liked the "politicians say the contrary"

but with the current shape of the Govt stability in its composition,...was wondering what are the changes of it happening 
but then, i thought there was a mention in another thread that Govt is, will or may consider use EPF as their piggy bank/national bank 

for me,...until that surprise became a "surprise",....i will still consider that news as a noise to sell the news

careful,...i think we BOTH have to stop this....
else later kena "Report" or kena comment 

Pandora box has been opened with no objection from syukur species, so expect more abuse in the future.

Usually if your an expat you should negotiate your package nett of tax which means all tax for the country ( Australia) is paid by your employer and arranged by your employer.

Companies sometimes dont regard you as an employee but as an external vendor ( e.g. cause you wont enjoy staff benefits like medical, etc) as such what they pay you could be without any tax deducted and they assume you will pay the relevant tax at the country of residence ( which in TS Wife Case Malaysia). So please check with your employer what they pay and did not pay,

Basically they treat you like engaging a foreign vendor and pay you a fixed sum per contract then you settled your tax at LHDN ( Malaysia)

If your working in Singapore ( means you stay in malaysia less than the prescribed period and is in Singapore for the prescribed period ) you will be a tax resident of singapore but not a tax resident of malaysia.
As such your not liable to LHDN. Proof can be via your passport. Transferring CPF money back is not taxable as long you have evidence and proof that its CPF money.
