If you had gotten seeds via selfing then you would have been the first to report it.

I've never heard of anybody successfully self-fertilizing these either. On the other hand I've not found anything conclusive that these are self-incompatible - other than the lack of reports of success in self-fertilization.
From what I've read this species wasn't included in the study of self-incompatibility in Australian Drosera.

I repotted some into a deeper pot last year. One of those is starting to flower this year. It looks like deeper pots may make a difference. I think Stephen Morley may have found one of the keys to getting these to flower. The plants in this pot are not making offshoots in the numbers that this species does in shallower pots.

Many-of-Us IN-This-Country Have Discovered THART Extremely WIDE-Pots Encourage The Adventitious Side-Runners to-Set More Tubers so-to-Speak IE The-Longer-They-R 'Allowed' to-Grow The More-Tubers You-Get so-to-Speak!!!! Great, did someone over there notice if you bend or push the D. gigantea bush halfway under the moist sand, every leaf under the sand sets a new tuber as the plant goes dormant? You can make several dozen clones each year using this method, a'la D. capensis. Timing is important, you want to do this when the plant has fully grown out the first set of leaves. When the second and third sets develop under the sand, the venation is different and this lets them each set a tuber. I also believe it has to be rather clear sand for some light transmission.

Once again I was fortunate to get a D. hamiltonii plant to flower. I repotted a few into a deeper pot last year. The produce fewer offshoots than they do in shallower pots, so deep pots may indeed be a factor in getting these to flower.

Have you had any luck so far? I'm not able to pollinate mine...

Looks like VFT flower. Maybe there is a timing issue? The anthers and pollen are not ready at the same time?

This species appears to be self-incompatible. I saved pollen from earlier flowers and tried pollinating with that as well as the same day's pollen. No luck. I have acquired what I am hoping is a different clone from the plants I already have and with a lot of luck both clones will flower at the same time next year.

Well here is something unexpected so soon, one of the D. hamiltonii Esperance SW Australia plants is starting to flower. Before my other plants of this species didn't flower until May-June. I'm still hoping this is a different clone genetically from my plants labeled only as Western Australia. If they are and I can get them to flower at the same time I'm hoping for seed. These are the two different batches side by side. There are perceivable difference which may not be actual genetically. Time (and a lot of luck) will tell. Esperance vs WA (left to right).

Flowers are coming up on my original clone. Maybe, just maybe I can make seeds.

And now (ta-daaa) - D. hamiltonii seed: Very few seed, and only from the flowers that were pollinated from the other plants. I may have waited too long to collect the seed but I've noticed that many of species that produce many offshoots seem to produce small seed amounts.

And now - seedlings!

The cotyledons appear to be covered with sessile glands. As a test for carnivory I placed at tiny speck of fish food flakes on one of the seed leaves. After twenty minutes it appears the leaves were secreting fluid - presumably digestive.
