Hi, Andrew -welcome to IIS. There's nothing boring about sea views with native wildlife, Mate - half your luck!
What you want is called a "spotting scope" - most are refractors, but Maksutov-Cassegrain types are available too. The main desirable feature is that they show things with the correct orientation, like binoculars (such niceties don't matter to astronomers!), so birdwatchers use them a lot. Prices range from very cheap (<$200), to very expensive ($2,000+). A tripod is essential for stable viewing of course.
You could try looking down the bottom of the Celestron section of Andrews Communications - they have several in your price range , and they also have other brands of spotters too:

Right side up and right way around viewing is possible with suitable astro scopes (refractor and Mak-Cas types), but requires the use of special eyepieces or diagonals, so in your price range, a spotter is the answer if you want more magnification than binoculars.
