I've looked up John & Jane Simcock/Sincock in South Australian Genealogy and so far I can't find anything about them. They didn't leave Adelaide for the countryside to farm and there's no blacksmith business listed for John, nor does William John marry in South Australia. I couldn't find them in the mining town of Broken Hill where lots of Simcock/Sincocks had stacks of children either (although John & Jane must have finished their family with William John as they were in their late 30s on arrival). I think they might have travelled to Victoria in search of work- there was still a goldrush there, whereas South Australia was settled into copper and tin mining (like Cornwall). Unfortunately even Australians can't access the Victorian BMDs without paying to look, so you'd need to use contacts or a facility like Ancestry to delve into Victorian records.
Sorry about the lack of success, but I did look hard!
Scratch the Victorians next!

In search of Simcock/Sincock who ended up in Auckland New Zealand, producing my cousin, Alan Simcock about 1952. I don't know how we are related!

I'm with Merlin. The kids probably know about Henry Kable and Susannah Holmes, but here's the official gumf!

Re: the "Annulment" of a marriage that had produced children. The Roman Catholic Church has been known to grant annulments because they do not recognise divorce formally. I have known cases where it was reasoned that a marriage "outside the church" was regarded as not existing in the eyes of god and the children were regarded as "god's gifts", not the product of their ungodly father! So there may have been an official annulment recorded in some sort of document held by the RC church.
