“We cope with it at Christmas, we cope with it at birthdays and we cope with the grandchildren asking questions about Lisa,” he told reporters on Tuesday.
“When it first happened, we were in complete and utter turmoil.
“It’s virtually the same as it was 20 years ago. She was in the wrong place at the wrong time, that’s what we believe.”
Mr Govan said he hoped whoever was responsible for his daughter’s disappearance and suspected murder, or anyone with information, would have a conscience and come forward.
“That’s what we’re living for all the time – that there would be a breakthrough,” he said.
Ms Govan’s mother Pat said she remained anxious and upset, but fondly remembered her daughter as “like a butterfly” fluttering around, adding she “lived life to the full”.
She said the whole family would be relieved if the case could be solved.
“It would be better than winning Lotto,” she said.
Mr Govan said he was satisfied to a degree with the police investigation, acknowledging that detectives could not reveal too much information.
In 2017, police conducted two raids in Kalgoorlie on properties linked to bikies, and a property in Perth.
Police Commissioner Chris Dawson said at the time that people associated with the club were a focus of the investigation but not the only focus.
A $250,000 reward remains on offer for information that leads to solving the suspected murder.
The family, which has previously tried using a medium to get answers, has launched a website in a bid to encourage anyone with information to come forward.
That is in addition to the Crime Stoppers plea for information.
Acting Commander Rod Wilde said any information, no matter how small, could provide a vital piece of the puzzle.
“We have active lines of investigation that we’re working on,” he said.
