Punctuality and reliability stand out, with reminders sent ahead of court dates, and communication before and after hearings is repeatedly mentioned.

Past his prime. Had my file for months, kept getting adjournments on 2 separate matters, telling judge and magistrate he only just received my file. Forgot court dates when I asked about them, struggled to find them. Told me legal aid won't pay for bail variations, not true. Accused me of secretly paying previous lawyer that did a variation application on legal aid. Ultimately couldn't use the court portal system so he said i will need a more tech savvy lawyer. Then told lsc we mutually agreed he wasn't right for me. Was nothing mutual he just wasted 6 months on a serious matter. The man needs to retire, don't use him to defend your freedom. Was no doubt great once upon a time. Seems to have become more of a social hobby.

The best and the first lawyer I got for my case Con O'Neil. He provides the best service he can and try's to help in any way. His prices are very reasonable and competitive with others but its worth to be his lawyer for any matter. Thanks Con O'Neil and I hope you keep up the best work.

I cannot thank Con enough for his time, effort and expertise in helping me resolve my legal issue. Con is a credit to his profession, at all times he was cool, calm and professional and always kept me reassured each step of the way. I could not have hoped for a better outcome. Thank you again Con, I won't forget it. Cheers!

Absolutely amazing lawyer. Very efficient and a genuine good person. He helped me with DUI chargers that I should have been locked up for. Thankfully through word of mouth from a previous customer of his I was guided down the right path. I will always cherish his leader ship and guidance. Thankyou so much Con

Very happy with the effort and work Con put in with my case, he was professional, but more important, a human. He is relatable and nice to be around, it's a breath of fresh air in the atmosphere that is our judicial system. I'm more than happy to recommend Con to anyone who needs a lawyer
