just on having lots of shares and the 'lose CG benefits' comment ...............you CAN be both a trader and investor (for shares) at the same time for ATO purposes (in the same tax year). You do need to demonstrate how the two groupings are separate though (and cannot be mixed together) and how the trader stuff is, for example, researched, follows trading plan, risk analysis etc etc to meet ATO trader rules. Most/some that do this also use two different brokers to gain further separation of the trader shares from the investor shares.
ATO website has really good and clear info on this sort of thing imo....and I have always found phone advice pretty good if u are prepared to keep asking questions to clarify your intentions (scary I know).
