Ending record-low rates, the bank cited inflation levels that had "picked up more quickly, and to a higher level, than was expected".
The move thrusts the bank to the center of a fierce political debate about the health of Australia's economy just weeks before the May 21 elections.
The opposition Labor party has seized on the prospect of a rate rise as evidence of a weakening economy and the conservative government's economic maladministration.
Prime Minister Scott Morrison, who is trailing in the polls, has insisted inflation is a result of worldwide trends, including the war in Ukraine.
The annual inflation rate is currently at 5.1 percent.
Like consumers around the world, Australians have been hit by soaring prices for food and fuels.
But house prices have been rising for years even as wages have stagnated. Sydney and Melbourne are among the world's most expensive cities in the world to live.

Higher interest rates will spell higher borrowing costs for millions of already heavily indebted Australians, in a country where real estate market speculation at times appears to be a national pastime.
Interest rates of two percent would cost the average homeowner about US$362 a month, according to financial services website RateCity.com.au.

This year's east coast floods cost an estimated Aus$3.35 billion (US$2.4 billion) in insured losses, making it the costliest flood in Australia's history, according to the Insurance Council of Australia.
