Tasman Sea

The Tasman Sea is the stretch of water that separates New Zealand from Australia. Eastern boundary touches several harbours and Cook Strait.

The Tasman Sea is informally referred to in both Australian and New Zealand English as The Ditch; for example, crossing the Ditch means travelling to Australia from New Zealand, or vice versa. The diminutive term "The Ditch" used for the Tasman Sea is comparable to referring to the North Atlantic Ocean as "The Pond".
