See if their economic projections are still valid when subsequent data is released by the ABS. For example last year when the GDP was released after the November RBA meeting, it was a catastrophic result and was worse than the RBA forecast. So the RBA reevaluated their forecasts downward. It would have been awkward for them not to cut rates when they are saying the GDP will be worse than expected. So indeed they cut the rates in Feb.
