Billabong is a brush script typeface household. This typeface has 4 styles and was released by Type Associates.

Billabong has its origins in the handlettered 40's and 50's script headings that seem to have withstood particularly in signage when style does not matter too much. Unlike today's scripts Billabong is securely spaced and Opentype typeface features allow for a myriad of ligatures to improve fit and evenness of color. Users can choose their option of strokes, accessories and ending flourishes for included focus and style.
Oh, and yes-- it is the font utilized on the Instagram logo. Smart choice!
