G'day Dave, great stuff posting your first trip and having it fill so quickly.
I know Tallarook pretty well and have run several trips from beginner to very difficult.
Here's a list of some good ones that aren't too hard.
(Assumption all vehicles have selectable low range, 4wds not SUVs)
Jenkins #1, #2 and Jenkins Link. Steep with some rocky sections but a stock vehicle will drive them.
Dicks and Stony Creek Tracks. As above.
Tehans 2, 3, 4, 5 and 6. All great fun, especially coming up 5. Steep in sections and can be slippery and rutted. Ideally suited to decent AT tyres or better but road rubber can do it. No probs if dry.
Horans, Brandy Corner, Brandy and Corner. Easy.
Cable Track can have a nasty bog section.
Rocky and Mountain Tracks. Challenging for stock vehicles but with spotting and good line selection they are doable. As suggested they are quite rocky and a bit steep.
Gravel Pit, Magazine and Caddell - some steep, rocky and potentially slippery sections but not hard. Good fun.
West Falls Rd - right up the north near the reservoir is steep and slippery clay when wet. Good fun though. Falls Creek Track is a tight and somewhat challenging little track that is fun as well.
Avoid Bills Track. Bog hole nightmare.
Don't touch Steep, Phone, Willies, Red Hill and unnamed/unmarked tracks off the top of Jenkins #1 & Tehans #2. They are particularly nasty tracks.
If you run into any trouble out there send me a message, I'm only half an hour away and can drive out and lend a hand.
