Wales finished bottom after losing all five games, including a record defeat against Italy in the final game.
“I made it clear when I was appointed by the WRU this was the job I always wanted and I needed the mandate to create a new team culture, to drive standards and challenge coaches, players and staff to build a team to make the nation proud,” said Lynn.
“That is something we will all do together, and developing more leaders is one of many steps on that journey.”
Lynn has named a 45-player summer training squad with a host of new faces from to underline his commitment to change in the senior national squad.
The coach wants to whittle his squad down to 30 players before heading to take on the Wallaroos in Brisbane on 26 July and then in Sydney on 1 August.
Wales beat Australia for the first time in their history at Rodney Parade in a warm-up last September before succumbing to a heavy defeat at WXV2 a week later.
On their return to the UK, Wales will have three weeks to shake off the jet lag and get ready for what promises to be the biggest ever Women’s Rugby World Cup, with the 10th edition being held across eight different venues in England.
Wales’ opening game is against Six Nations rivals Scotland on Saturday, 23 August in Salford before further group games against Canada and Fiji.
