You base your maths on 7 applications.

Let's not forget that of the 5 domains in question, only 2 of the 7
companies successfully won the ballot...

perth.com.au - AUSSIE DESTINATIONS (2) PTY LTD
casino.com.au - AUSSIE DESTINATIONS (1) PTY LTD
newcastle.com.au - AUSSIE DESTINATIONS (2) PTY LTD
darwin.com.au - AUSSIE DESTINATIONS (1) PTY LTD
airliebeach.com.au - AUSSIE DESTINATIONS (1) PTY LTD
