Option 1 - AMEX - https://amex.acetravelinsurance.com/AU
This insurance is expensive and it covers less things while you're on holiday. It doesn't cover stealing, permanent disability, travel services provider insolvency etc. On the essential column, the accidental death benefits is $0 which isn't helpful at all.
Option 2 - QBE - https://www.qbe.com.au/personal/quote/travel/international
This insurance is only $179.10. It is cheaper than the last one and covers more things as well. The only thing it doesn't cover is snow sports however that is unnecessary to cover anyway.
Decision
I choose option 2 - QBE. This is because it is cheaper and it covers more things than the AMEX one which was expensive and useless on a holiday. Travel insurance is important and should be highly regarded in planning a holiday because we can never predict what can happen.
