I would think that AN aren't silly enough to compete with J* on the route. There will be a few moans from the regulars, especially in regard to seating, the E170 has plenty of leg room compared to the A320/B737.
Its strange isn't, the NT Government are pouring taxpayers money into J* to help it set up, while AN has successfully financed its aircraft without going to the Government for assistance.
The government aviation advisor has done well, Virgin were paid to start the ASP service, which ceased when the money ran out, then Tiger collected more cash and forced Bruni to cease services. When competition came from J*, Tiger quickly pulled out.
