I don't see why not. By the way, you don't need to be Blackmores.... as long as it made in Oz is fine. Recentlly I bought from Coles where it is on sale for $11 a bottle of 400 capsules.
"Blackmores fish oil 1000 odourless 400 capsules" in an Eastwood Chemist is very cheap .. something like AU$18 only. Also, cos it is for my in-laws to intake, some known brand will be better.
I searched some websites in hk and Watson in HK sells the same product (same brand same content) with 90 capsules only for HK$200.
