Still, a minority are betting the RBA could remain on hold on concern that pushing the benchmark rate to a record low 2 per cent could further fuel a bubbling housing market.
"With a housing boom in full force and with many Australians now using their superannuation pension accounts to finance further real estate activities, the RBA is justifiably concerned about the negative effects of lower rates on the already dangerous housing bubble," Boris Schlossberg, managing director of FX strategy at BK Asset Management in New York, said in a note.
"That's why (today's) decision may be closer than the market thinks and the monetary authorities in Sydney may choose to remain stationary for another month more."
BK Asset Management is betting the RBA will either leave rates unchanged or lower them and move to a neutral bias.
The RBA decision is scheduled for release at 4:30pm New Zealand time. Australia also has data on the services industry, new home sales and trade today.
