"I am really excited again. I am really happy with how things have gone over the last five days," Boyle said.
"I am still a fair way off world records so it's possible to improve more. I am happy with the improvements I have made. It is not going to be easy to improve from here but I am still very motivated and determined to improve and I am excited to keep swimming to see how good I can get."
Boyle believes that while the longer distances are her target, getting faster is also important.
"I am pretty competitive worldwide in the 800 and 400 but at the same time improving my 200 time will help my speed for the 400 and in turn the 800 too.
"I have developed my speed which was a big plus this week as I did not know I could go that well in the 800. But at the same time I've learned from the 400 where I did not do as well as I wanted that I need to make sure I can still back up after a big race."
Success has also created other challenges.
"Learning to cope with all the things out of the pool is a big part. This week I was drug tested every night, sometimes urine and blood tests. I was getting back to the hotel at midnight and 1am, and then eating meals late after that but getting up very early the next day to prepare for the heats.
"I have struggled a bit with this. There are definitely things to juggle at big meets. If you get a medal you can't warm down until you have done that and your media, and you have to report to drug testing before you go to the pool so it all takes a lot of time that you have not prepared for."
Boyle will enjoy Christmas before setting her sights for 2013.
"I will have a few days out of regular training to freshen up my mind until after Christmas and then be motivated to be back in the pool. The target will be to prepare for the world championships in the middle of the year in Barcelona."
In other swims Ingram, 27, was 15th fastest in the 200m freestyle in 1:57.38, producing her best time of the year to complete a strong championship for the veteran North Shore swimmer, coached by Scott Talbot.
Earlier Howick Pakuranga's Corey Main was 17th fastest in heats of the men's 200m backstroke in 1:54.70, to be a fraction outside his best with the top eight through to the evening finals.
