Both aged in their 80s and with various health conditions including Mrs Whan's severe respiratory problems, any exposure to COVID-19 could be potentially devastating.

"Our family have told us they want us to stay isolated to keep us safe," Mr Whan said.

"They're looking out for us."

To complicate the situation further, this year, the couple have been trying to sell their home in San Isidore.

Every time a viewer, real estate agent, or inspector comes to their door, the couple retreat for days in isolation.

"When people come through, we move into our caravan outside," Mr Whan said.

"We've been told that 72 hours is safest, that's how long it takes for the virus to die on most surfaces."

Mr and Mrs Whan are also sanitising anything - including groceries or mail - before it enters the house.

But those around them, friends and even strangers have gone to lengths to ease their health burden.

"Our dear neighbour, Dean Sutton, he's been very kind and allowed us to keep the caravan on his property," Mr Whan said.

Last Thursday, the Whans organised a building and pest inspection. But a communication error meant that the pest inspector did not turn up. The re-scheduled appointment on Monday would mean that the Whans would spend an extra three days in their caravan, in near-freezing overnight conditions.

So, their real estate agent Michelle Wilcox contacted Wayne Kenyon, owner of Advanced Pest Management, who cut his family holiday short to drive back to Wagga.

It was the most self-less care they have witnessed after almost 40 years in Wagga.

"It's wonderful, people talk about the kindness of random strangers. I've never liked that term but in this case, they have been good neighbours to us in the Biblical sense."
