35 YEAR OLD SWIM SCHOOL NEEDS UPDATED LOGO ! Help!!

This is what Australian Swim School was looking for in their logo design

Hi creative people! My swim school needs a redesigned logo. I have been in business for 35 years and our logo has major brand value but needs a little updating as we launch a new location. I am a little tentitive about changing what works however we want to stay current and go for a updated look. The old logo with a new look is what I am after!
THE company name is : AUSTRALIAN SWIM SCHOOL Please go to www.australianswimschool.com to see our current logo. We are known for our koalas and I would like to keep at least one in the logo. Our colors have been red,white and blue. I would like to see the current colors or change up and use blue, green, browns. the final design should communicate Australia ,waves,koala(s), swimming longevity, consistency and a modern updated look. I am open to a subtle change of current logo or a new look altogether Good luck!! Read more
