Yep if you really want to start now,dripped in over time as the Bull mkt is looking dodgy , stale atm. Id be tempted to sit and watch for the next month or so and leave the cash earning a little interest(its low but so is inflation). The signs of a big correction/possible flight to safety (indeed happening now) could accelerate anytime. Our reserve bank taking off .5 % of the cash rate is a pretty big flag imo. All about ones level of risk and ones level of reward.

Its time in the market but getting the timing right (roughly) will magnify returns manyfold.
