A National Health Service Trust spent almost £9,000 sending three members of staff to a conference in Australia, it was disclosed.
Lancashire Care NHS Foundation Trust sent three delegates to the International Conference on Early Psychosis held in Melbourne between October 20 and 22.
A spokeswoman said three members of the Trust's early intervention service attended the event.
She said: "Staff flew out on economy flights and stayed in standard rooms in the Holiday Inn.
"The total cost for each member of staff, which includes flights, visas, accommodation, meals, travel to and from the airport and attending the conference was £2,885.
"The conference provided an opportunity for staff to hear about the latest research into early intervention services and bring back best practice examples which can be brought into Lancashire Care's service, ultimately improving the service for patients and their carers.
"This is in line with Lancashire Care's commitment to research and evidence-based practice."
She said three consultant psychiatrists also attended the conference to present research papers but this was not funded by the Trust.
