Pyramids beach (WA 777) is a 1.4 km long beach that commences against the northern beachrock boundary of Florida beach and terminates at the 500 m long Dawesville Channel training wall. The channel is part of the large Port Bouvard and Dawesville development, which cut the 1 km long, 200 km wide channel to connect the Harvey Estuary with the Indian Ocean. The beach is backed by the Pleistocene calcarenite dunes rising to 40 m, which are now covered by the southern Southport part of the development. The beach commences immediately north of the reef with a low tide terrace and waves averaging just over 1 m. The waves pick up in height toward the channel and the northern half has a centre beachrock section with a boundary rip, then a 50 m wide bar cut by a central beach rip. In addition there is a strong permanent rip against the training wall, and a small spur groyne off the wall. The spur causes the beach to spiral round to face south against the wall. There is surf on the small reef break at the southern end and beach breaks along the bar. The groyne has been built to trap sand at the northern end of the beach. This sand is then periodically pumped under the channel to the northern side, to assist in the longshore sand transport. This will need to be an ongoing process otherwise the northern beaches will be deprived of sand and continue to erode. The beach is patrolled by the Port Bouvard Surf Life Saving Club, founded in 2004. As there are usually a few rips along this beach, particularly towards the northern end, make sure to swim only when patrolled and in the patrol area.The northern side of the Dawesville Channel has a shorter training wall, just 50 m in length, with a 150 m long groyne located 100 m to the north and a seawall linking the two walls and continuing for 500 m to the north. The training wall has been built to control or train the flow through the channel, while the groyne is designed to presumably stop sand moving southward and into the channel. The seawall is a result of the severe beach erosion that has occurred since the channel and walls were constructed. While sand is pumped under the channel from Pyramids beach, erosion is continuing on the northern side, as it is starved of the sand that would normally move northward along the coast. This sand is part of a beach system that extends northeast for 11 km to Robert Point at Mandurah, where the sand moves around the point and into the next long sediment cell. In between are 13 near continuous beaches (WA 778-790) most separated by low beachrock reefs and calcarenite outcrops. The first seven beaches are located along the 5 km of northeast-trending shore between the channel and Falcon.Between the northern wall and Falcon, 3 km to the north, are four beaches (WA 778-781). The first two have been heavily modified by the walls and groynes.
South Melbourne and Port Melbourne Life Saving Clubs patrol a 1.5 km section of beach between the Kerferd Road and Lagoon piers. The reason for having two clubs is that the boundary of South and Port Melbourne Shires crosses the beach midway between each club. The low beach is backed by Beaconsfield Parade, as well as a low seawall and promenade. While the South Melbourne Surf Club was established in 1927, the Port Melbourne Life Saving Club was formed in 1913, but it now occupies a new building. Both clubs incorporate dressing rooms and kiosks.The beach faces the south-south-west, and can receive moderate waves during strong southerly winds. When these occur, they maintain a 100 m wide beach fronted by a 50 m wide bar, that is usually attached to the beach, with occasional rip channels. The rips are only active when waves are breaking over the bar.
Burnie is the second largest city in northwest Tasmania with a population of over 20 000. It has a major port and associated industries and is a major service centre. The town is located on low ground in lee of Parsonage and Blackman points, with the port in lee of Blackman Point. Wharfs and breakwaters extend nearly 1 km east of Blackman Point providing more shelter and anchorage for shipping. Today the port and its facilities form the eastern boundary of Burnie, while West Beach forms the northern (Fig. 4.235). The beach is located adjacent to the main business area and is backed by both a road and railway line. Wedged in between the railway and the sand is a reserve containing the Burnie Surf Life Saving Club, which was established in 1921, a large elongate car park , playground and picnic facilities (Fig. 4.236).West Beach (T 1087) is a 700 m long northeast-facing sandy beach bounded to the west by the low Parsonage Point, while a seawall, Blackman Point and port facilities form the eastern boundary. In addition rocks lie across the centre of the beach, just west of the surf life saving club. The beach is composed of medium sand, which combines with the usually low waves to produce a moderately steep narrow high tide beach, which widens up to 100 m at low tide.
