The tournament was won by France's Julie Greciet who won by two shots over South African Lee-Anne Pace.
Both Garret and Campbell finished with final rounds of 66 for their respective placings.
For Garrett it was her best LET finish in nearly two years and moves her to 64th on the 2014 Order of Merit while Campbell, who has been twice runner-up this season, now stands in 5th position on the money list.
After ten years in Japan, Campbell has focused her attention on Europe in the last two years and the former Australian Amateur Champion is continuing to show her class.
