Yes ur capital losses are forwarded. So say u make a capital loss of 100k in 2017 financial year, then say in 2020 you make a capital gain of x amount that is deducted from ur 100k.

Ur capital losses stay with u forever untill u make a capital gain.

U must have lodged ur capital losses with the ato for that year. Its automatically rolled over year on year.
