The sharemarket closed higher for a fifth straight session, reaching five-year highs despite disappointing jobs data.
The benchmark S&P/ASX 200 Index was up 8.1 points to 5242.5 and the broader All Ordinaries gained 7.6 points to 5238.2.
OptionsXpress analyst Ben Le Brun said the market had made tentative gains on soft volumes.
"There's been some negativity centring around the unemployment rate, but it looks as if the momentum [from market rises earlier this week] is just enough at this stage to keep us tracking on the upside," he said.
Official figures showed that the unemployment rate rose to 5.8 per cent in August, from 5.7 per cent in July, in line with economists' forecasts. But the 10,800 fall in the total number of people with jobs was the opposite of expectations of an increase.
The data sparked a selloff in the dollar, which dived more than US1¢ to US92.4¢ in late trade.
Investors had been driving up the dollar, buoyed by solid Chinese economic data, easing concerns over Syria and increased business confidence.
Mr Le Brun said investors were awaiting next week's US Federal Reserve policy meeting for any indication that the US will start tapering its stimulus program.
"Maybe that's starting to become a little bit more of a focal point today, ahead of jobless claims in the US [overnight]," he said.
