I prefer low tide as the exposed foreshore is usually a lot more interesting.
Queensland's Sunshine Coast has some fantastic locations for sunset / moonrise opportunities. Point Cartwright is one of my favourites and indeed, a number of our Trekabout Photography Workshops 'Mountain to Beach Experience' photography workshops have been worked in with full moons. The resulting photographs have been awesome.
But you don't need to be on the Sunshine Coast to enjoy a full moon-rise at sunset. I have encountered amazing sights in the Red Centre for example with incredibly coloured moon-rise opportunities.
So how do you plan these shoots to be there at the right time. There are a number of tools that I use to good effect. The first of these is called The Photographer's Ephemeris or TPE. This is a free download for your desktop PC, Mac or laptop computer. You can also purchase the TPE app for iPhone and iPad and Android devices are also catered for.
TPE is easy to operate. In a nutshell it provides you with a map overview of your planned camera location and a graphic illustration of sunrise, sunset, moonrise and moonset. You do need to be online for the mapping which is where the app on a portable device is a great advantage. You can check out TPE by following this link...
It just so happens that the next full moon is on Thursday 2 August, and the moonrise is at 5.34pm with sunset being a few minutes earlier at 5:22pm. This has potential for some awesome seascapes as the moon rises out to sea into the pink afterglow of the sunset. Rest assured I will be on a foreshore somewhere :-) That same morning will also be a good for sunrise / moonset combination with the moon setting not long after sunrise.
Unfortunately, the tide won't be perfect as for sunset it will incoming and around 3/4 in. I don't think I'll let that stop me though.
