Busselton Aero Club already has Avgas avbl.
Perhaps because the supply of Jet A1 is a 'bigger deal' installation, and they want it known....I simply quoted the article as written.
Maybe they just want to clarify to potential operators that Jet A1 will be avbl on site, so no need to 'tank' it in.
The 'nimbys' won't like looking at those relatively large holding tanks etc.
Perhaps they will be screened by more trees....
Cheers
