It's only been a few months since the end of Jetstar Asia, but now Jetstar is looking to make a bigger push back into the Singapore market. Starting next March, the low-cost carrier will fly between the Lion City and Bali … but that won't be the end of the journey.

In an interesting twist, the Singapore–Bali services will only be one leg on direct routes connecting through to the Sunshine Coast and Newcastle, a pair of smaller airports in regional cities that wouldn't normally expect to see Singapore services – so, what's the plan for Jetstar?

On this week's Australian Aviation Podcast, Jake, David and Bethany take a look at Jetstar's new Singapore routes, what they might do for the cities they serve, and what might be next.

Plus, the plan to link Western Sydney Airport to high-speed rail – will it ever happen, and what will come of it if it does?
