Ventia Services chief executive Dean Banks says the group is struggling to find people for cleaning and catering jobs as it delivered a big jump in net profit in its first full year of trading.

The company, which floated on the Australian Securities Exchange in late 2021 at $1.70 per share, reported an 880 per cent increase in annual net profit to $191.2 million from the $19.5 million it earned in the year-earlier period.
