It might be cold this time of year but thats no good reason to stay out of the water. The SE coast of Australia has some amazing dive sites and this is the best time of year to visit them. There is quite a large seal colony this year of about 40 seals in total just outside Jervis Bay. Seeing them in the wild and diving with them is an unforgettable experience. We dived on nitrox 32 and collected some debris, fishing line, spears, and rope netting in the area where the seals live. There are also old bomb shells at the site because the armed forces used to use it for target practice.
