Professor Petrovsky in Australia commented on this quite extensively.
He has developed previous successful SARS and Ebola vaccines as well as working on coronavirus vaccines and received extensive US Govt research funding over many years.
Prof Petrovsky also made clear he was not saying that the virus was made in a lab, but he also said he found it strange that so many researchers said it was definitely not created in a lab. It was too early to say that it was not developed via gain of function research or other lab recombination methods which could make it appear a natural viral mutation. Additionally he stated that certain elements of the virus made it very remarkable for a naturally mutated virus

Professor Petrovsky, who is the Chairman and Research Director of Vaxine Pty Ltd, said COVID-19 has genetic elements similar to bat coronaviruses as well as other coronaviruses.
Flinders University Professor Nikolai Petrovsky has completed a scientific study, currently undergoing peer review, in conjunction with La Trobe University in Victoria, which found COVID-19 was uniquely adapted for transmission to humans, far more than any other animal, including bats.
Professor Petrovsky, from the College of Medicine and Public Health at Flinders University who has spent the past 20 years developing vaccines against pandemic influenza, Ebola and animal SARS, said this highly unusual finding left open the possibility that the virus leaked from a laboratory.
“It was like it was designed to infect humans,” he said.
“One of the possibilities is that an animal host was infected by two coronaviruses at the same time and COVID-19 is the progeny of that interaction between the two viruses.
“The same process can happen in a petri-dish. If you have cells in culture and you have human cells in that culture which the viruses are infecting, then if there are two viruses in that dish, they can swap genetic information and you can accidentally or deliberately create a whole third new virus out of that system.
“In other words COVID-19 could have been created from that recombination event in an animal host or it could have occurred in a cell-culture experiment.”
Professor Petrovsky was originally modelling the virus in January to prepare a vaccine candidate. He then turned his attention to “explore what animal species might have been involved in the transmission to humans” to understand the origins of the virus - and had a “surprising” result when none were well-adapted.
“We found that the COVID-19 virus was particularly well-adapted to bind to human cells and that was far superior to its ability to bind to the cells of any other animal species which is quite unusual because typically when a virus is well-adapted to an animal and then it by chance crosses to a human, typically, you would expect it to have lower-binding to human cells than to the original host animal. We found the opposite so that was a big surprise,” he said.
