I second Lead Balloon’s advice.
Nowra airspace typically becomes deactive between Friday lunchtime till Monday morning (check notams and atis). If deactive, plan on going the long way around Jervis Bay, ie, the coastal side. On the south section, run along the beach from Sussex Inlet, Wreck Bay, around to the decommissioned Cape St George lighthouse. On the north side, over to Point Perpendicular lighthouse and the amazing cliffs. Stay over water and at 500’ looking across at the cliffs you’ll be amazed. Then, get a bit of height and check out the Beecroft bombing range as you head towards Currarong. At Drum & Drumsticks you might see a seal colony sunning themselves on the rocks.
If Nowra is active, feel free to ask for a clearance other than the GA lane, but expect to be given only the GA lane if there is any hint of activity at JB airfield (or there’s a warship inside JB). In my experience I’ve found Nowra ATC far more friendlier and helpful than Williamtown. The GA lane has a couple of doglegs in it, so you need to know where you are and where you’re going.
Victor 1 is amazing, just don’t be one of the numptys who drift into CTA between Maroubra and Ben Buckler. The real estate from Jibbon Point all the way up to Barrenjoey is incredible. Lots of aircraft traffic though, especially on nice sunny weekends, so also need to keep a good look out and listen out. If you are keen, put a plan in and carry out a “Harbour Scenic One” flight to check out the harbour, CBD etc. on your way north (or south). Details in ersa.
On your way up the central coast, if you’re tracking coastal, be aware of traffic around Lake Macquarie airport, as it is almost right on the beach! Get your clearance from Willy Delivery and then expect to hold at Nobbys Lighthouse before tracking nouthbound coastal via the GA lane. If you’re in the right place at the right time you might see some hornets buzzing around.
On the reverse trip home, as LB suggested, try the alternate GA routes if you want some different experience, or if you like the beach runs, just do that.
Southbound through Nowra, if deactive, run along the inside section of JB. Pick it up at Callala Bay, then run down to Husky, Hyams Beach, and HMAS Creswell – an amazing Navy base in an incredible location. From Creswell, overfly JB airfield and pick up the coast at Wreck Bay then continue southbound coastal. Half of JB went up in a bushfire this week, so the area will look a little different than normal!
Further south, both Moruya and Merimbula are right on the beach, so be careful of traffic, especially Rex at both places and parachutes at Moruya. Speaking of parachutes, there is intense parachute activity at Wollongong City, just NW of the lighthouse. The jump plane operates out of YWOL. They make multiple drop calls on both ywol and Syd centre, so no excuses for bumbling through an active drop zone unawares.
Have fun!
