Rather then a bank deposit if you want something relatively safe you could always buy bank shares
Most have traded within a certain range over the last 10 years so not super high risk. Plus you can get 6-8% fully franked dividends. A 7% divi is actually equivalent of 10% as it already has 30% tax paid for you.
However i would probably wait to see if the market crashes a bit over the next few months and then by into an indexed fund.
Or if you want to possibly lose all your money or maybe triple it you could always invest in micro caps and mineral explorers
