Australia-listed wagering company TopBetta Holdings Ltd. saw a four-fold increase in its total revenue in the fourth quarter of 2017, thanks to a robust retail business in the country.

In a regulatory filing, TopBetta reported that its total revenues leaped to AUD6.9 million ($5.5 million) in October to December 2017 period, a 401 percent increase from AUD1.377 million ($1.11 million) in the same period last year.

TopBetta’s October to December 2017 revenues were also 95 percent higher than the AUD3.55 million ($2.87 million) it raked in during the previous quarter.

Todd Buckingham, managing director at TopBetta, described the Q4 figures as “healthy revenue growth” that “slightly” exceeded the company’s expectations.
