That's a tough one, and highly dependent on the level of risk you are prepared to take.
We had a similar dilemma. Almost a year ago we sold our house in the expectation of a crash taking place in 2019. Since then we have our money parked, and just waiting for the crash, which is taking longer than we thought.
Because we were not prepared to risk our house money, we were forced to shuffle among a number of bank based introductory accounts that pay around 3% annually. Because the RBA's cash rate is a mere 1.5%, you cannot get better than 3% without substantially increasing your risk. We have searched, and could not get 5-7% with any meaningful or enforceable capital guarantee.
