Photos of evidence seized from the home of an alleged Adelaide wife-killer, including sex toys and condoms, have been released by a South Australian court.

Peter Rex Dansie is accused of murdering his wife Helen by drowning her in a pond at Veale Gardens, in Adelaide's southern parklands, on April 16, 2017.

Supreme Court Justice David Lovell today released more evidence tendered in the trial, including photos of items found in Mr Dansie's Waterfall Gully house and videos of police conducting interviews with the 70-year-old at his home and the alleged crime scene.

"When Helen had her stroke 22 years ago, I quit my job at the ABS and spent the next 22 years looking after her. This isn't just looking after her, this is 24/7," Mr Dansie told officers.

"I've travelled extensively with her, I've looked after her. I didn't do this under sufferance, I did it because I wanted to. I wouldn't see any benefit in then going and killing her."

The photos released by the court show the contents of a suitcase Mr Dansie was allegedly about to take to China about a month after his wife's death.

During his opening address in May, Crown prosecutor Jim Pearce said Mr Dansie had searched the internet for "sexual role-playing games", "thigh-high boots cheap sale" and "sexy six-inch stiletto sale" in the weeks before Ms Dansie's death.

Mr Pearce said the day before Mr Dansie was scheduled to fly to China, police searched his home and found a suitcase packed with condoms, Viagra, sex toys and lingerie.

Mr Pearce also said Mr Dansie engaged in "steamy" online chats with two women, allegedly telling one he would "like to see more photos of her in bra and panties".

In one of the newly released videos, investigating officers take Mr Dansie back to the Veale Gardens pond on the night of the alleged murder and ask him to retrace his movements.

Mr Dansie also told police his wife's nursing home fees were "quite high", and said he would not have been able to make a claim against his late mother-in-law's estate with his wife now dead too.

"While I'm wealthy, this would have been, in my view, poetic justice to be able to claim that back," he told officers in the interview.

As part of the defence case, Greg Mead SC called two witnesses who told the court about the care Mr Dansie provided to his wife.

"The first thing that stood out to me was when we went around for dinner I asked if I could bring anything … and Peter said, 'Can you bring something for Helen, some flowers or a book'.
