Chemical Toilets

I dont see salt water as being a problem you may have to use a bit more chemical than you do in fresh water boats use chemical toilet all the time and alot of them have salt water flushing the inside of your toilet should be all plastic so should be no damage the only thing i would keep an eye on is if you have any scres in the unit keep them oiled if you use alot of salt water so ithey do not rust, Happy travels

Avoid getting sand in the tank as it may damage the seals/pump.

Sounds like you will be having a great trip all the best. An increasingly common issue with chemical toilets is disposal of the contents. You cannot drop the contents into country septic tank systems as it kills all the good bacteria in the septic. I am getting lots of reports from outback/country towns where caravanners and campers have dropped their chemical toilet contents and it brings the small towns sewerage system to a rather unpleaseant halt. Similiar issues arise with emptying the contents into long drops, dry toilets etc.

Whilst slow in coming, there are now caravan and camping sites, on the Eastern coast mostly as well as some towns, that have specific places to empty chemical toilets. Sadly there are no maps produced, that I am currently aware of, that identify these services.

Enjoy the trip

Just be aware that you will probably get a foul odour if you use salt water for flushing (more foul than otherwise). Apparently it has something to do with a reaction between uric acid and the salt - anyway, it was bad enough to make me convert the boat to use fresh water flushing!
