Covering many of the plant types found in Australia, the Australian National Botanic Garden in Canberra covers 35 hectares. With paths winding through the garden, you are able to experience many of Australia’s habitats in one place.
Getting There
We drove to the Garden and parked in the carpark there. As with most Canberra attractions, this is a paid parking area, so you need to purchase a ticket at one of the machines. From here we walked to the visitor centre where we got a map before starting on our walk.
What to See
We chose to walk the Main Path track because it covers all of the major areas of the Garden. A staff member suggested that we commence at the lower rainforest boardwalk, as the misting effect was about to start. This was a great suggestion and was the highlight of our visit. As we walked through the ferns of the rainforest, a mist drifted through, cooling us off, as it was a hot day, but overall the area was impressive.
After passing through the rainforest we saw banksias in flower before taking a diversion to the Red Centre and rock garden. While walking we passed several water dragons basking in the sun. They must be used to visitors as they did not run off as quickly as others we have seen. We were lucky to get several good photos of them before they decided to hide.
For those interested in birds, a huge viewing platform, the paperbark tree house is available for use.
We found the path to be an easy walk, with no steep grades. The walk took us around 45 minutes with plenty of stops for phots and to look at the plants. A great place to visit, especially the rainforest section.

Taking you through the rainforest canopy, the Sea Acres Rainforest Boardwalk is a 1.3km loop that starts and ends at the Sea Acres Rainforest Centre. Unfortunately, when we visited (December 2022), maintenance on the boardwalk cut the loop because of storm damage. This was not too much of a problem because we retraced our steps and walked the second half from the Rainforest Centre. So, we got twice the walk for the same price.
How to Get There
Located only ten-minutes’ drive from the centre of Port Macquarie on the NSW mid-north coast, Sea Acres Rainforest Boardwalk is easy to get to. Well sign posted and with a large carpark, it’s easy to find and access. If you need a drink or something to eat, there is a café at the Visitor Centre with indoor and outdoor seating.
The staff are very helpful explaining the walk as well as what we should see along the way.
The Boardwalk
Rated a Grade 1 track, the boardwalk is flat and wheelchair accessible for its entire length. With numerous stops and information boards, it’s an easy and educational walk. At around 7m off the ground, we could see into the canopy while still seeing the understory.
Keeping you out of the mud and fallen leaves is a bonus if you don’t have hiking boots, while you still get to experience the rainforest. The information boards also provide a guide to the different trees and their role in the forest.
What Did We Think?
This was a quick and very easy walk. A great way to fill in an hour. At the end we visited the café to relax and grab a snack while admiring the rainforest. It would be great for families with kids because it means you’re not walking them through the undergrowth. For people with mobility issues, it is excellent as it’s flat and accessible.

The Urunga Wetlands and Boardwalk are the result of a ten million dollar project to rehabilitate an old mining processing plant. The result is a beautifully restored wetland and the containment of the tailings and their heavy metal content.
History of the Site
In 1969, Broken Hill Antimony Pty Ltd established an antimony processing plant on the site. Located at Hillside Drive, Urunga the processing plant extracted the heavy metal antimony from its ore, stibnite. After the ore was delivered to the site, it was crushed, and the antimony removed using complex chemical reagents and equipment.
Although the processing produced an estimated 400 tonnes of product, it generated 16,000 tonnes of waste. These waste tailings were rich in heavy metals including antimony, arsenic, lead and reagent residues of cyanide and cresylic acid. Poor management of the tailings resulted a spreading plume of waste contamination the surrounding wetlands.
Although sold to a private owner after closure in 1974, no clean-up or remediation work occurred.
A combination of soluble leachate and insoluble sediments impacted the wetland causing largescale die back of the swamp paperbark (Melaleuca quinquenervia) and damage to the habitat of the wetland for birds, plants and fish.
The Rehabilitation Process
The Environmental Protection Authority declared this a remediation site in in 2002 because of long-standing concerns by the community, environmentalists and Bellingen Shire Council. With the owner unable to fund the remediation work ownership of the site transferred to the NSW Government as Crown land. In 2011 a remediation order was placed on the site.
Around four hectares of land needed excavation. A total of 36,400 tonnes of contaminated soils and sediments required removal. Stockpiled and then treated with chemicals to stabilise it, the waste now sits in an engineered containment cell constructed on-site. Remediation resulted in a total of 224 tonnes of antimony, arsenic, lead and mercury removed from the environment.
Only a grassy mound now indicates where the containment cell is located, but beneath that surface is an engineered structure with 15 different layers.
The Site Today
If you were unaware of the site’s history, you might think the area had not required rehabilitation because it looks so amazing. The initial walk winds through replanted forest before reaching the wetlands. At this point a 150m boardwalk crosses the water, allowing you great views of the melaleuca forest on the far shore. Along the way, sedges, lilies and other wetland plants line the shores.
On the far side of the boardwalk the track continues completing a loop to the carpark. Along the 450m of walking track, information boards show the layout of the area, provide you the history of the site and show what wildlife you may see.
How to Get There
A carpark on Hillside Drive, Urunga has plenty of room. However, there are no facilities here apart from rubbish bins, so bring your own food and refreshments.
Swimming and Canoeing
Visitors should stay on the paths to avoid disturbing wildlife and allow the vegetation to establish. Although the water appears clean, traces of heavy metals are still present, so swimming and boating are not permitted.
What Did We Think?
We enjoyed the walk and were amazed how well the rehabilitation turned out. This was a great place to visit while we were in Urunga.
