Toyota was the top selling brand in Australia in May 2013 and also had the top two selling models: Hilux and Corolla.
The Corolla knocked Mazda's 3 off the best selling passenger car perch it has occupied for months.
Last month’s total industry sales of 96,788 units was almost par with May 2012 with only a 0.7% increase, according to official VFACTS data from the Federal Chamber of Automotive Industries (FCAI).
But year to date sales were up 4.5% to 454,953 new vehicles.
The top five models in May were the Hilux (3,665 units) and Corolla (3,640), the 3 (3,054), Mitsubishi Triton (2,606) and the Hyundai i30 (2,512).
Three of the top 10 selling vehicles in May were light commercial vehicles, four were small passenger vehicles and two were locally produced. Sales of private diesel powered light commercial vehicles continued to show strong growth with May sales (5,466) up 46% year on year.
The top five May brands were Toyota (19,003), General Motors' Holden (8,293), Mazda (8,135), Hyundai (8,027) and Ford (7,243).
Sales of small and medium SUVs showed strong growth last month with sales of 6,266 small SUVs, up from 5,239 in May 2012, and 11,361 medium SUVs versus 9,426. Year to date growth was 20.3% for small SUVs and 15% for medium.
Toyota Australia's sales chief Chris Beuth said the automaker expected to grow its overall market leadership in June - traditionally the industry's strongest month of the year.
"In May, Toyota's total of 19,003 sales was substantially more than the combined totals of our two nearest rivals," Beuth said.
"Dealers have now sold almost 84,000 Toyota vehicles this year, which is more than 40,000 ahead of any other brand.
"Toyota expects to pass 100,000 sales for the year during June, delivering more than 20,000 vehicles - a level no other brand has achieved in a single month."
