With the risk of posting a few facts on PPRuNe:
1. There has been no receiver, or administrator appointed to Jetgo!
2. The "Application for winding up order" is a long way off any winding up. You will find it relates to an ongoing dispute regarding to passenger tax rebates that were offered by Dubbo Regional Council to get Jetgo to fly there originally, but subsequently reneged when a new mayor was elected following the Council merger". Jetgo is yet to have its day in court.
3. Tamworth stuck the boot in when Jetgo pulled out, but has been paid in full with all forward booked passengers BNE-TMW also fully refunded.
Both Tamworth and Dubbo take a "boots and all" approach to debt collection using Sydney based lawyers these days!
