About



Harrison Markwick is a NSW Class 1 licensed real estate agent and auctioneer with Century 21 Rouse Hill. Ten years in the profession — built on a simple public standard: communication, service, and doing exactly what he said he would do.
How he got here
01
2013
From Century 21 Double Bay in 2013 — a high bar, harbour-side volume, and the habit of doing the work properly.
02
The move
He brought that standard west into the Norwest. Family homes, growing streets, and vendors who wanted a straight conversation more than a harbour pitch.
03
2018
In his first 18 months at Beaumont Hills with Century 21 Rouse Hill, Harrison became the No. 1 agent in that market. The suburb firsts that followed were a continuation, not a coincidence.
From Century 21 Double Bay (2013) to No. 1 in Beaumont Hills in his first 18 months with Century 21 Rouse Hill. That is the path — not a slogan.
He is best known across the Norwest for a run of Beaumont Hills results that still get cited: the first ever $2 million sale in the suburb (7 Glasshouse, 2019), the first $2 million single-level (82 Brampton, April 2021), and that No. 1 ranking. Those are not marketing adjectives. They are suburb firsts.
He holds both the sales licence and the auctioneer’s ticket, which is why WICK Auctions exists: so the person who listed your home is the person who calls the room.
The path into real estate was not the usual one. Harrison is a seminar creator and trainer, the author of Mighty Young Minds, and a former disability support worker. He still works from the same premise he took into those rooms: tell the truth, remove what is weighing the decision down, and then do the work.
He lives in western Sydney and sells across the Norwest — Kellyville, North Kellyville, Beaumont Hills, Rouse Hill, The Ponds, and the streets around them. If you are selling, the first conversation is a confidential appraisal. No listing pitch. The number, the method, and whether he is the right person for the job.

Seminar creator and trainer. The same discipline — tell the truth, then do the work — is the one vendors feel on a campaign.
Years as a disability support worker sit underneath the sales licence. Service is not a marketing word. It is a habit.
