One of the best growth shares on the Australian market in the last decade has been Domino’s Pizza Enterprises Ltd. (ASX: DMP). Its shares have provided investors with an average annual total return of 39.1% since 2006.

Let’s put that in context. Any lucky investor that invested $50,000 in Domino’s shares in 2006 would have seen their investment grow to be worth over $1.3 million today.

Unfortunately though because of this incredible track record Domino’s shares are in high demand changing hands at 62x full year earnings. This is a little rich for myself personally, so I’ve picked out three growth shares which I believe are trading at a reasonable price. Here they are:

Blackmores Limited (ASX: BKL)

Shareholders of this rapidly growing health supplements company have seen the value of their holdings drop by over 45% so far this year. This leaves its shares trading at just 20x full year earnings, which I feel is a bit of a bargain considering its growth prospects. These declines are largely down to concerns over changes to Chinese import regulations and a disappointing first quarter outlook by management. Although it expects earnings to grow at a rapid clip this year, it does expect sales to be lower year on year in the first quarter. It is going to be an uphill battle for Blackmores, but I feel confident the company will deliver.

iSentia Group Ltd (ASX: ISD)

Thanks to the growing popularity of its Mediaportal platform and a better-than-expected performance from its recently acquired King Content business, iSentia reported a 23.6% rise in full year net profit after tax to $24.3 million. I was especially pleased to see strong growth in the Asia market. The Asia/Rest of the World segment delivered a 51% increase in revenue year on year, giving me confidence to believe that the segment has a bright future ahead of it. Right now its shares are changing hands at 20x estimated FY 2017 earnings estimates according to CommSec. With analysts expecting earnings to grow by an average of 30% per annum for the next couple of years, this seems like a more than fair price for an investment today in my opinion.

Touchcorp Ltd (ASX: TCH)

At just 13x trailing earnings this provider of secure transaction processing, payments and data services is looking remarkably cheap. Touchcorp recently reported a 21% rise in half year revenue to $22.5 million thanks largely to an ever-growing number of agreements it has in place with the likes of 7-Eleven, HICAPS, Optus, and Afterpay Holdings Ltd (ASX: AFY). It’s worth noting also that as well as providing its technology to Afterpay it also has a major holding in the fledgling company. That holding has now grown to be worth approximately $133 million today by my calculations. Furthermore this year the company started to expand its presence overseas with potentially lucrative deals with Cornèr Bank in Switzerland and Change Up in Scandinavia. All in all I feel this is a fantastic growth share to invest in today.
