The gains came after Wall Street shares rocketed 11% on Monday as investors welcomed fresh moves to deal with the worldwide financial crisis.
Investors were helped by news the US government wanted to put in place its $700bn bank bail-out quickly.
Australian Prime Minister Kevin Rudd has now announced a A$10.4bn ($7.3bn) economic stimulus package.
It will allow for one-off payments to the country's low-wage earners and pensioners and follows earlier announcements of guarantees of bank deposits for three years.
According to Mr Rudd, the strategy "will strengthen the national economy and support Australian households".
By lunchtime, Sydney's S&P/ASX200 was up 219 points at 4399.7, and the Australian dollar had strengthened against the US dollar, trading four cents higher than on Monday.
In New Zealand, the stock market rose 6.7% by early afternoon.
In the US, President George W Bush is due to make a statement shortly before markets open there later on Tuesday.

Rescue plans
On Monday US Treasury and Federal Reserve Bank officials met the chief executives of some of America's biggest banks, to work out details of the US government's $700bn (£400bn) bail-out package.
The US has said it was also getting ready to follow in Europe's footsteps and purchase stakes in financial institutions.

European governments have said they are putting up to 1.7 trillion euros ($2.3 trillion; £1.3 trillion) to protect the continent's banks through guarantees and other emergency measures.
The sums are a maximum, and might not all be spent if the financial crisis eases.
So far Germany has approved a bank rescue plan worth up to 500bn euros, France will spend about 350bn euros, the Netherlands has pledged 200bn euros, Spain 100bn euros, and Austria 85bn euros.
Italy said it would spend as much as was needed, without giving any exact figures.
The bulk of the European money will be used to guarantee lending between banks - part of a plan agreed this weekend by the 15 nations that use the euro.
The cash will also be used to take stakes in ailing banks, with the UK government saying it would inject up to £36bn of taxpayers cash into Royal Bank of Scotland, Lloyds TSB and HBOS.
