80,000km scheduled service

No. Time to find an independent servicer, or DIY.

Also, I would not rush to change the brake fluid. You'll have to research the fuel filter location, as a separate fuel filter is not a feature of North American Prius which has the filter integrated within the fuel tank.

 

I think third gen Australian shedule also calls for fuel filter change, and I recall reading that there is nothing different about their fuel filter location: it is in the gas tank, per North American vehicles. In other words, it's a major task, to get at, and not cheap. Not sure why Australia (only?) recommends fuel filter change: poor regulation of particulate in gas?? On the assumption that second gen Australian cars are similar, and that fuel filter change might be overkill:

I'd waive the the fuel filter change. Maybe it's needed, or maybe it's some regulations driving this maintenance requirement?? see how much they want for just the brake fluid change, and DIY the air filters.

With our 3rd gen, with my wife's help I did the brake fluid change in about an hour, using 2 pints of of Toyota DOT 3 brake fluid, and a few jury-rigged tools, nothing expensive or esoteric. This may or may not be possible for you, dealership or independent mechanic may be preferable. Assuming 2nd gen procedure is similar, I would think around $100 US would be reasonable.

Note with third gen, and presumably also with second: you do need to follow a specific procedure to avoid messing up the electronics. Either you use Techstream, or there is a chicken-dance procedure, to set the car in invalid mode. One of @NutzAboutBolts videos pinned in the third gen maintenance section covers this. I would be cautious using an independent mechanic, if they're not conversant with the intricacies of the Prius brake system, specifically second generation.

I'll attach a pdf from 3rd gen repair manual regarding brake fluid change, just to give a sense of what's involved. The document explains the procedure, including the order to do the brakes, in an extremely verbose and confounding manner. This is what it is:

 

I wouldn't bother with the fuel filter either. I'm not a big DIY guy but the in-cabin and engine air filters were 5 minute jobs or less for me to do myself. The filters were cheap at the local auto parts store and easy to change. Didn't even get my hands dirty.

That leaves you with the brake fluid. Unless the price comes down very drastically for performing only that service, I wouldn't change it yet.

 

The US 3rd gen schedule doesn't mention brake fluid change I think. Toyota Canada says 3 year or 48K km's (30K miles).

Honda's always said tri-yearly regardless of mileage.

 

Hmm, Aus and Can dollars are virtualy on par: yes that's reasonable. The supplies would likely amount to about 2 pint of Toyota DOT3 fluid, around $15~20, but you're paying for expertise, labour, their overhead/equipment, and specialized software.
