I feel the show pulled something random. Just before nationals, Rin invited Haru to go to Australia.
The series is a bit different from Kuroko's Basketball in that Free is more career and school oriented. Kuroko's Basketball is about the sport and the drive to win with friends.
I felt Rin's homestay father had good Australian accent and voice acting. The mother's voice sounds so monotone.
It was a good episode.
Another similarity between Kuroko's Basketball and Free is lots of English dialogue. I always notice the English audio is lower than the Japanese audio. It's hard to hear the English words and their accents.
Apparently real swimmers for the inspiration in the Aussie episode:
I also want to share one interesting blog post. Check it out here.
I have no knack for analyzing shows/movies, so I'm really glad that there are people with brains out there who can point out these things.
I tried watching real basketball after Kuroko's Basketball. I couldn't get into it. I'm just really weird. I feel Figure Skating does count as sport. Same with Nascar racing. I remember a racer mentioned a lot of folks mock racing for not being a real sport. He explained that racing is a sport and requires a lot of training.
