C130's can land on Tuvalu.Tuvalu has a problem because their airport can't accept C17 or C130's (I think a C130 could land, empty max). Anything else is going to take a long time to shuttle any supplies. Vanuatu has a large international airport that regularly takes commercial flights, Tuvalu and Kiribati are less lucky, and have a bigger problem moving things around within nation. Kiribati because things are so spaced out.
I imagine once the patrol boat is at Tuvalu it will be tasked with shipping supplies around Tuvalu and medical runs etc.
Of course a $600 million project to replace them is up in the air at the moment too.

Given Au and NZ new sealift assets I would have thought they would have been keen to utilize them.
A few years ago a RAAF C17 flew desal equipment to Samoa, and the RNZAF C130 flew it the rest of the way to Funafuti.
Funafuti International Airport has a ex WW11 runway of 1500 metres (from Wiki)
