Best and cheapest way to short ETFs intraday

Hi. I’m looking to get ready to short aussie ETFs like STW, VAS and A200 mostly just for intraday asx exposure. The inverse ETFs BEAR or BBOZ don’t fit the bill.

Are CFDs or options the only way to get short exposure to STW, VAS or A200 and what would be the mechanics and fees for doing it those ways?

I haven’t done much short selling so it would be great to know the exact steps e.g. Buy CFD such as xxx on platform yyy after ASX open and sell before close. My feeling is the fees and snake oil of CFDs and options will make it prohibitively expensive but please let me know if I’m wrong. If shorting the underlying indices like XJO is the only cost effective way to do it, please point this out.

Thanks!
