This is a very simple open-source extension that will enable you to switch between tabs using Ctrl-Shift-[ and Ctrl-Shift-].
Originally, it also included a rough implementation of Apple's Natural Scrolling, Chrome OS now includes it out-of-the-box. To enable, just go to:
chrome://settings/pointer-overlay
and select Australian scrolling.
