The awards recognise annual growth as a percentage by revenue. Vocus is an internet transit operator and telecommunications provider to the wholesale market that listed recently on the ASX.
Vocus recorded in percentage terms six times the growth of No.2 hotel search engine, Hotels Combined. M2 Telecommunications was the only other telecoms provider in the top 10.
InTechnology Distribution was ranked No. 8 with a 311.90 percent growth.
Vocus, which operates across the Tasman, reported more than 500 percent growth in profit before tax in its latest audited annual report. Last month the company bought Melbourne data centre operator E3 Networks for $5.9 million.
Vocus chief executive officer James Spenceley, pictured, who Ernst and Young recently awarded Young Entrpreneur of the Year, said the win meant a lot for staff.
"Mostly recognition for the hard work that it has taken to grow the company at that rate over the three years," Spenceley said.
"[It was] very well received internally. [I] had a number of the key and early staff at the [awards] and thanked them in the speech. They are really excited by the recognition by such a firm and award program like Deloitte."
Many CRN Fast50 winners were represented in the Deloitte annual list: Megabuy, Anittel, ispONE, Stratatel, Sense of Security, Revolution IT, Thomas Duryea, Matrix CNI.
Bulletproof Networks (No.38), the only cloud provider, owed its 43 percent growth to organic growth, said executive director Lorenzo Modesto.
Distribution Central (21) was recognised with a leadership award for growing more than 120 percent while earning more than $50 million in revenue.
Internet companies dominated the Deloitte list (19) followed by software (15) and communications or networking (10). More than half the finalists were from NSW (28), while South Australia and ACT recorded none. And more than two-thirds were private companies.
A number of companies returned this year: it was M2 Telecommunications fifth year in the list, while ispONE and Revolution IT have been awarded four times and Sense of Security and Thomas Duryea listed for the third time.
