A spectacular waterfall in the Southern Highlands

Minnamurra Falls in Budderoo National Park.
To get to Minnamurra Falls park at the Minnamurra Rainforest Centre - at the end of Minnamurra Falls Road in Jamberoo. It is a 31 minute drive from Robertson, or just 8 minutes from Jamberoo. It is possible to catch a bus or taxi to this location.
The Minnamurra Rainforest Centre is open from 9am to 4pm daily, and is closed on Christmas Day. This is one of two waterfalls in the list that require an entry fee to visit - the price at time of writing is $12 per vehicle per day (paid via the self-serve machines in parking area), or $4.40 per adult and $2.20 per child if travelling via public transport.
There are multiple walks that start here, but to see the falls you need to follow the 4.2km "Minnamurra Falls Walk". The hike is steep with an elevation gain close to 200m, but it is along an elevated boardwalk or paved pathway for the majority. The walk itself is as beautiful as the destination - I recommend taking your time and allowing a minimum of 2hrs to take in all of the sights and sounds of the rainforest. There are multiple viewing points and rest areas along the way before you arrive at the viewing platform for Minnamurra Falls. If you are lucky you might even see or hear a lyrebird.
Parts of Minnamurra Rainforest are accessible via wheelchair, but this does not include waterfall, as it is a steep climb. This is a great family-friendly hike near Sydney!
Flushing toilets, picnic tables, drinking water, and light refreshments are available for purchase.
It is best accessed via a 12 minute drive along Belmore Falls Rd from South St in Robertson. Accessing Belmore Falls Rd from the Pearsons Ln/Myra Vale Rd side will require you to drive across the river via a concrete causeway, which often has water flowing over the top of it (especially if the waterfall is flowing well).
That is the route that Google Maps took me on my first visit - insisting that the access road from Robertson was closed - but on arrival I realised that was incorrect. If you go from the Myra Vale Rd side, there is not enough space to turn around at the creek crossing, and if you decide not to drive through, you would need to reverse a fair way back to turn around.
The road from either direction does become unsealed at some point, but it seems to be fairly well maintained. Take care when passing other vehicles as the edges can be very soft and give way. Belmore falls is free to access! There is a good amount of parking at the end of the Hindmarsh/Belmore Falls access trail.
Unfortunately, hiking to the base of the waterfall is now prohibited, and in peak periods people have received infringements for ignoring signage. Fortunately, there are multiple lookouts along a short walk that safely follows along near the cliff-line, offering great views into the valley, and of the impressive multi-tiered Belmore Falls.
There are drop toilets and picnic tables available near the Hindmarsh Lookout parking area.

There are two main walking tracks that begin at the visitor centre: the East Rim Walking Track, and the West Rim Walking Track. The West Rim Walking Track offers better views of the waterfall itself. From the car park, it is approximately a 250m walk along a boardwalk/paved pathway to a lookout at the top of the falls. This is as close as you can get to the waterfall, and the lookout offers great views down into the valley below. To get a better view of the entire waterfall (including the lower section) continue down the trail for approximately another 400m to the Jersey Lookout. After the first lookout, the boardwalk ends and you will be walking along a more typical hiking trail, which can become muddy after rain.
This second lookout is, in my opinion, the best place to view Fitzroy Falls.
There are many facilities available at the Fitzroy Falls Visitor Centre, including flushing toilets, picnic tables, drinking water, and even a cafe. The visitor centre and first lookout on the West Rim Walking Track are wheelchair accessible.
There is much more to see along the West Rim Walking Track, including more waterfalls at the Twin Falls Lookout, and The Grotto.
To get to Nellies Glen it is a 12 minute drive from Robertson. You will drive along Jamberoo Mountain Rd before turning onto Cloonty Rd, and eventually following the signs to a parking area at the end of Nellies Glen Access Rd/Trl. The roads are sealed and usually suitable for 2WD vehicles the whole way - however there is sometimes water flowing over a concrete causeway on the way in. NSW NPWS will generally close the road in as soon as they have any access concerns, so if the road is open then it is likely the water crossing will only be shallow with a gentle flow. Use your own judgement on arrival to determine if it is safe.
Access is free in this area of Budderoo National Park! From the parking area, there is a short (approx 150m) walk to the bottom of the waterfall. The trailhead is well signposted, and the trail itself is easy to follow. This is mostly just an uneven dirt pathway and it can become muddy after rain.
Drop toilets and picnic tables are available nearby the car park.
There are also longer walking trails that begin from the Nellies Glen Picnic Area.

Carrington Falls in Budderoo National Park.
To see Carrington Falls, park at the picnic area located at the end of Thomas Pl Rd - it is well signposted to Carrington Falls as you approach from Cloonty Rd. It is a 13 minute drive from Robertson along sealed roads, which do become narrow and winding.
From the parking area, there is a short, well signposted 600m loop walk. This trail is a mixture of paved walkways and boardwalks, it takes you to three viewpoints where you can see Carrington Falls and the Kangaroo Valley. There is also a point where you can access the Kangaroo River above the waterfall, nearby some smaller cascades.
There are drop toilets and picnic benches in the picnic area.
Carrington Falls is in very close proximity to Nellies Glen, making this area perfect for a waterfall day trip in New South Wales!
