The Home and Away star and National Rugby League player Myles, who got engaged last March, exchanged vows in front of friends and family in a garden out the back of her family's Melbourne home on December 23.
James told New Idea magazine: "I am so very, very lucky to have Nate in my life. And it was the best day."
He added: "I loved it and wouldn't change anything. It was perfect."
The 20-year-old actress wore a Steven Khalil drop-shoulder French lace wedding gown embellished with Swarovski pearl beads and ostrich feathers and a blue family heirloom brooch in her hair.
Myles said: "She looked beautiful. I don't think I've ever seen her look that great. My favourite part would be when her dad lifted the veil off - I was blown away. Honest to God, I tell her every day how lucky I am to have her and I will always love her to death. I don't think I could love anyone as much as I do her."
James admitted that she did have some last-minute nerves, saying: "My moment of freak out was when I drove in and saw everybody. But then I saw Nate. That's all I wanted to do all day and when I did, I thought it was all going to be okay."
The couple were rumoured to have split late last year, but a spokesperson for Myles soon rubbished the reports, saying that their relationship was "still on track".
James's Home and Away co-stars Jodi Gordon, Samara Weaving and Esther Anderson all attended the event, together with Gordon's sports star fiancé Braith Anasta and Myles's teammate Todd Carney.
