Aggressive growth portfolio at 20

Hi been lurking for the past couple weeks and the information here has been invaluable , I’ve been investing as much as I earn from my part time job since 18 ,I’ve got currently 20k sitting in ivv but going foward I want to be more diversified and I would try to stick to this split.
Ivv: 65
Pmgold: 5
Vge: 10
Vas: 10
EXUS.asx: 20

Any liquidity problems with EXUS as its only made recently ?

Goal FIRE by 40
super long timeframe atleast 20years
Currently earn 35k before tax annually and no debt except student HELP loan
Any insight or comments is really appreciated thank you
