Looking along the beach towards the landing place of Captain James Cook (1770), which then was to become the landing place for Captain Phillip when he arrived in 1788.
Upon arrival, Phillip decided that Botany Bay (this body of water) was not suited for the intended purpose, and so he sent scouts to find a better location. The one chosen was the next bay north, and that became known as Sydney Harbour, which is the other side of the tall buildings in the centre of this picture. Not far away physically, but a very different environment now. And a much better harbour back then.
Hearing a great noise, drew attention to these two vessels approaching the beach. The area in the background is Port Botany, which has become the major container terminal for Sydney, and is taking other freight from Sydney Harbour.
As the vessels come closer, they appear to be hovercraft. The downtown area of Sydney is in the background; the tower in the centre is Sydney Tower Eye,

Contact for the second hovercraft.
Hovercraft safely ashore, and a paraglider in the background. This is looking "inland".
And the airport is just across the bay, so it's not surprising to see planes taking off in this (southerly) direction. It also reduces the noise impact. My flight in the previous day was in the opposite direction to this.
