A member of the British relay teams at last year's World Championships, Turner was one of the stars of the show at the British Gas Championships booking an individual spot and two relays for London.
The 19-year-old saw off Olympic medallist Jo Jackson and former double Commonwealth champion Caitlin McClatchey to claim 200m freestyle gold and an individual place at the Olympics.
She will also compete in the 4x100m and 4x200m freestyle relays, alongside Jackson and McClatchey and multiple European and Commonwealth medallist Fran Halsall.
And having recorded lifetime bests in both the 100m and 200m at the Olympic Aquatics Centre, where last month she was on a training camp with the rest of the British team, Turner can't wait to make her Olympic bow.
She said: "I always wanted to be on the cover of the Swimming Times and I've achieved that now.
"At the British Gas Championships obviously I was really happy because I made it individually, which was totally unexpected. I only really came down to make a relay so to win was pretty amazing.
"Whatever I did for the trials worked really well so I just want to keep doing the same thing and keep the intensity up.
"My family support me so much and help me out and do so much for me, so to know your friends are there supporting you and willing you on is just really nice - you can't ask for any more.
"To compete in a home Olympic Games is a once in a lifetime opportunity. A lot of athletes around the world don't get this opportunity; they can go to three or four Games and still not be in their home country so I am really lucky. I'm really exciting it is coming up.
"It is just exciting and good to finally do an individual since I have gone along to do a lot of relays."
Having completed the week-long training camp alongside her British teammates Turner insists she is ready for the Games, and admits that team spirit will play a key role in London.
She added: "We discussed a lot about the Olympics - what to expect and it was good to have the sponsors down to support us and let us try out the suits.
"It was great for everyone to get together and mix all the different coaches and see what everyone else does in training. Also we were able to bond outside the pool as well as inside which really helps.
"The trials were a massive confidence boost and it just shows that anyone can do it and you just keep moving on from there and see what you can do in London."
