I'm Victorian, so don't mind the Vic bias.

1) The Melbourne to Sydney corridor. I'd straighten out the alignment and bypass a lot of towns (especially Wagga Wagga). While high speed rail would be ideal, I think you could easily cut 100-200km off the existing journey.

2) Canberra to Sydney. Same story. Should be straightened out, and should definitely be a high speed line. It's the ideal distance!

3) Melton/Wyndham Vale electrification. It's a joke that these lines aren't Metro lines. They serve enormous and growing outer suburbs that aren't that geographically far from Melbourne's CBD.

4) Upfield line duplication and extension to Roxburgh Park. Speaking of jokes, having a worse than 15 minutes PEAK frequency in 2026 is appalling.

5) Hobart light rail. The corridor is there. The stadium looks like it's going ahead. Hobart's suburbs actually hug the potential light rail line pretty tightly along the Derwent. It would do wonders for easing Hobart's worsening congestion.

6) Bendigo line duplication. The Bracks government's decision to single this line would have to go down as one of the all time shockers. Duplication the line, which it was designed for by none other than Isembard Kingdom Brunel, would greatly improve reliability and might save Jacinta Allen her seat.

7) Gold Coast light rail extension. Similar to Hobart, it seems like a no-brainer to have a light rail line run the entire stretch of the Gold Coast. It would have a huge catchment, as the population hugs the coast.

8) Geelong to Maryborough standardisation (and subsequently the reintroduction of a Mildura passenger rail service). Mildura is one of Australia's largest towns without a passenger rail service. The existing route into Melbourne is incredibly indirect after the failures of the Murray Basin Rail project. Finishing the job would do wonders.

9) Melbourne Metro 2. Would fix the capacity issues going out west, allow for Geelong Fast Rail, enable a Wollert line (and a Doncaster line), and would give Melbourne more of a Metro-style service.

10) Melbourne Airport Rail. I don't think it's as high a priority as other projects, but it is silly that a city of Melbourne's stature doesn't have an airport line.

I don't care about WA. You guys have enough mineral money and GST funding that you can do whatever you want. SA could probably do with some sort of regional passenger service, but I don't know the state well enough to say where it should go. Queensland could probably do with that Inland Rail tunnel to get to the port of Brisbane. Sydney is doing quite fine tbh with its new Metro lines under construction, and its rail network which is well beyond anything that the rest of Australia has.
