Ocean temperatures are fairly stable compared to the land, so that is a big change for the ocean. Being territorial is no barrier at all to the population moving. In fact it may encourage it, as there will always be outcasts traveling south looking for a home.
You don't need to "force" sharks and fish to move. They do it naturally. They are always actively looking for new homes. Even coral does. With coral, you are not really limited in any way by how fast they can move, only how fast they can grow. Each year they cast their offspring to the currents, and they drift far and wide. So if a new location becomes warm enough for coral, it will start growing. In a few years you will see it, and in a few more it will be prominent, and in a few more it will take over the reef.
I have definitely noticed more sharks. Go back more than a decade, and I would spend a few hours swimming around on offshore reefs, often dragging dead fish. Barely recall even seeing a shark. These days I am lucky to get the fish in the boat without having to compete against the sharks.
Now that’s an interesting observation, and it makes me think the sharks are starving?
I haven’t been fishing for decades as I used to love going out with dad in his boat to fish in Port Phillip Bay. I can say I’ve never seen a shark in all those earlier years, except for small gummy sharks.
I decided recently for my birthday, I’m going on a fishing trip (none other family member are interested

) so it will be interesting to see what happens, and what stories there are to tell.
Stay tuned!
BTW I have seen huge stingrays so close to boat ramp in shallow water. Usually in the evenings.
