What the RBA's split decision means for rate rises

The Reserve Bank has lifted the cash rate to 4.85 per cent, the highest since late 2008, adding about $90 a month to minimum repayments on a $600,000 mortgage.
The RBA says excess demand and the risk of people accepting fast-rising prices as the new normal drove the fifth rate rise, alongside fuel costs.
The board was split six votes to three and economists are divided on whether rates will rise again, so is this the last increase?
