A typical adult great white shark measures 4 to 4.8 metres (13 to 16 ft) with a typical weight of 680 to 1,100 kilograms (1,500 to 2,450 lbs)
there have been sharks that were over 7metres in length, but they are gone now hunted and killed.
Great white sharks live in almost all coastal and offshore waters which have a water temperature of between 12 and 24° C (54° to 75° F), with greater concentrations off the southern coasts of Australia, off South Africa, California, Mexico's Isla Guadalupe and to a degree in the Central Mediterranean and Adriatic Seas. One of the densest known populations is found around Dyer Island, South Africa where much research on the shark is conducted. It can be also found in tropical waters like those of the Caribbean and has been recorded off Mauritius.It is a pelagic fish, but recorded or observed mostly in coastal waters in the presence of rich game like fur seals, sealions, cetaceans, other sharks and large bony fish species. It is considered an open-ocean dweller and is recorded from the surface down to depths of 1,280 metres (4,200 ft), but is most often found close to the surface.
In a recent study great white sharks from California were shown to migrate to an area between Baja California and Hawaii, where they spend at least 100 days of the year before they migrate back to Baja. On the journey out, they swim slowly and dive to up to 900 metres (3,000 ft). After they arrive, they change behaviour and do short dives to about 300 m (1,000 ft) for up to 10 minutes. It is still unknown why they migrate and what they do there; it might be seasonal feeding or possibly a mating area.
In a similar study a great white shark from South Africa was tracked swimming to the northwestern coast of Australia and back to the same location in South Africa, a journey of 20,000 kilometres (over 12000 miles) in under 9 months.
sharks are superbly adapted to the seas and they can survive anywhere, but they need to have prey animals in these waters such as turtles, seals, dolphins etc. if Newcastle has such prey animals then may be a shark could survive there.

The first rule about sharks is, forget all rules about sharks.

No and no at the current time. Who knows about 2500 years in the future though?
