Turn right: From the intersection, this walk follows the GNW arrow post[24] directly away from the face of the 'Brisbane Waters National Park' sign[25] along the clear track[26], keeping Mooney Mooney Creek to your left. After about 100m, this walk crosses a green timber footbridge[27], then about 200m later comes to a small clearing and intersection just before the road bridge[28]. Here the walk turns right, following the old management trail uphill through the tall forest[29] for about 200m then heading around a locked gate[30]. Just past the gate, this walk turn left and heads up the short steep bank[31] to come to a T-intersection with the old Pacific Hwy, at a large gravel car park[32] marked with 'Mooney Mooney Creek' Trackhead[33] (just east of the Mooney Mooney Creek bridge).

Continue straight: From the end of the dirt road[55] (that branches of Karool Rd, just north of the Mooney Mooney Bridge), this walk heads uphill along the trail and around the locked gate[56] next to the timber 'Brisbane Water National Park' sign[57]. The trail leads uphill for about 200m to where the trail bends left to pass over the crest of the hill (passing a faint track on your left[58]). Here the trail leads down the other side, still keeping Mooney Mooney Creek to your right[59] for another 400m to come to an intersection marked with a GNW arrow post[60], beside a large grassy clearing[61] (no camping).
Veer right: From the intersection[62] just above the clearing, this walk follows the GNW arrow post[63] down along the track, keeping the clearing and campsite[64] to the right. The track soon leads over a small flat timber bridge[65] then over the next 60m, the track heads under the high tension power lines (past the caution sign[66]) and then along a short section of timber boardwalk[67]. About 20m later, this walk veers right at a Y-intersection[68], then continues along the mostly flat track beside Mooney Mooney Creek for about 300m, to cross a small rocky tidal creek[69]. The track then continues through the tall forest[70] beside Mooney Mooney Creek for about 600m, passing a couple of she-oak stands[71] before the track then bends left and comes to an indistinct intersection[72] beside a timber and metal footbridge[73].
(8km) Footbridge → Ausburn Creek crossing
Continue straight: From the campsite[80], this walk follows the clear track north, keeping the wide Mooney Mooney Creek to your right. The clear, wide and mostly flat track leads alongside the creek[81] for about 1.2km to come to the southern bank of Ausburn Creek[82] (about 130m past a rock wall[83], on your left), a few metres above its confluence with Mooney Mooney Creek[84]
(9km) Ausburn Creek crossing → Lower Mooney Mooney Dam
Continue straight: From the bank of Mooney Mooney Creek, this walk crosses the wide rock platform[91] and creek[92] to find the track again on the other side[93]. This creek may become impassable after heavy or prolonged rain. Here the walk turns left and follows the rocky track that leads gently up alongside the creek through the pleasant forest[94]. After a little over 1km, the walk comes into view of the tailwater of the dam[95] and then past a fenced cutting[96] (on your right), the site of an old pump house[97]. About 60m past this fenced area, the walk leads up along the now widening track to find the edge of the fenced lower Mooney Mooney Dam wall[98].

At the bottom of the timber staircase the walk comes to an intersection with a short path leading to the 1st Fall Lookout.

Turn left: From the intersection, this walk follows the 'Bottom Falls' sign down the hill (keeping the main valley on the right). The track soon heads along a sandstone platform (passing a metal arrow) and down the stone steps to come to a timber platform. The walk follows the platform and heads down the staircases. At the bottom of the timber staircases, the walk turns sharply right to follows the stone steps down to the creek (On the way the track passes over a slippery unfenced rock ledge, care is needed). Just before the creek there is a 'No Track Beyond this point' sign. The steps then lead to the rock platform at the base of the falls. (The rock platform can be slippery and there is an unfenced cliff) At the end of this side trip, retrace your steps back to the main walk then Continue straight.
