Brisbane's Lifeline Bookfest is back at the Brisbane Convention and Exhibition Centre from June 26 to July 4.

Due to COVID-19 the event will be cashless and people will be asked to bring their own bags.

Lifeline is hoping to raise $1.5 million from book sales, with 2,000 volunteers needed to help out.

Lifeline Queensland retail general manager Jamie MacKay says the last two Bookfests haven't been able to take place due to COVID-19, so they have got more books than previous years.
