It's probably not the worst option out there, TBH. If it's one of those "You must get there" and you know there's no fuel, then it makes sense to save your back. That being said...
Last year I flew from Gladstone-Townsville and tankered fuel in a steel jerrycan so I didn't have to try to source fuel on arrival - though Christian (from Donnington Airpark) did say he's happy to facilitate that if needed from the local servo, but it was just one less thing I wanted to fluff about with. If you have the payload, I'd consider that over a trolley and collapsible bladders depending on your W+B.
But I have to ask, what went amiss in planning this hypothetical trip? Surely you're not just going to this unattended airstrip just for the sake of it, you'd be meeting someone, or picking someone up, so there's the option for a lift there?
The other thing I'd mention is consider is putting the call out on FB, you may well find someone sympathetic to your plight who'll give you a hand. For example: a few months back, a BK-based pilot asked about public transport from our local airport to an adjacent town, and while it is there, it's extremely limited. I said "If you're coming up around this day or time, let me know and I'll take you in, I need to nip over there anyways". He flew up, parked the Arrow in my backyard, I drove him across to drop off his parcel while I picked up a bike for Mini-Me, he brought me a pie in return and he flew home.
Another example would be a mate got stuck with the weather coming home from Qld a little while back and lobbed in to our local airport. Called me up and after a bit of Tetris, we squeezed his Maule into our hangar and I dropped him in town where he had arranged a ride back to the coast. Picked him up couple days later and he flew home under blue skies.
These aren't isolated examples, so don't be too afraid of asking for help. If @Bosi72's on the right track, you won't be the first to need help at that particular strip, so FB or even here can provide an answer as to what other pilots have done in the past.
Re the transport of fuel (or other DG), anything that is a "Placard load" requires marking and specific training, and what defines a placard load varies depending on the material. Which is how you can get away with carrying a couple of gas bottles in your car - it's under the limit. From memory, it's any DG in bulk (a container of more than 250L) or more than 1000L or Kg all up, or any quantity of Class 1.1, or 6.1 or 7 (though it's been 20 years since I did my DG course, so cut me a little slack if I'm getting forgetful!). There's nothing particularly special about carrying a jerry or two of fuel - in NSW or elsewhere so don't get too wrapped up about "following the roolz", or any cow cockie who goes to get fuel for his gennie would be a criminal.
