I gained confidence and support

I finished a double diploma in Management and HR Management earlier this year (2016).  As I am not a natural studier this was quite an undertaking, however with the superb support and patience of Rosina (my trainer) I found I had excellent skills and was actually quite good at it.

I have been able to implement the subjects directly into my work environment and improved systems and processes to achieve higher outcomes. Having worked in my current role for several years I now feel more confident in my position with the additional knowledge I have gained that matches my position description.  Thanks Rosina – you are a legend.

Rosina Aston guided me on a journey of self-learning I never believed I could achieve

Back in 2010 I signed up for a Certificate IV in Business, but soon after meeting Rosina and having our kick off meeting she gave me the self-belief to upgrade to an Advanced Diploma in Management. Rosina worked with me one on one as a coach and mentor, keeping me focused on the end game of COMPLETION and I did.

I enjoyed my time learning with Rosina that 6mths later I returned to her as my trainer of choice to study a Diploma of Project Management. Rosina’s genuine care factor for her students blew me away and made me feel compelled to work harder, she has a never give up attitude. Rosina and I have become friends after my  education experience with regular phone calls to discuss new world problems, training opportunities for my team or just a great person to call when I need advice and vice versa.

I was inspired by Rosina Aston’s enthusiasm for learning which encourages me every day
in my own learning journey to reach for GOLD and make each learning opportunity count

Rosina Aston has been a wonderful trainer, coach and mentor to me and many other colleagues and employees within our organisation. She has been working with us since 2006, taking many of us through Certificate IV and Diploma level courses, as well as WH&S and TAE training.

Working with many other private organisations and government bodies Rosina understands the importance of tailoring the course content and real life examples to your business and future business outcomes. Rosina has the ability to quickly identify additional training support for those in need and will deliver! She is able to encourage consistent work ethic in order to keep the pupil engaged throughout each training module from commencement to completion.

In my own experience and from direct employee feedback I would recommend Rosina as a solid training partner to any business for specific Cert IV to Advanced Diploma level training needs. Rosina has a ‘can do’ attitude and this resinates through her enthusiasm and care for each pupil.

Lisa Floyd – HR Manager at Plantation Homes

Rosina’s honest enthusiasm and ability to know just the right way to help encourage each and every student to reach their target is only one reason why I will continue to choose her as my trainer.

Rosina was a major factor in my ability to complete a Dual Diploma of Business and Human Resource Management.

Her ability to adapt to each students training style and genuine interest to see each and every one do well, helps to build confidence within even the most reserved of us.

The flexibility in the way in which the training was delivered is a major bonus. The one on ones, the phones calls, the emails and the “study days” helped make the finish line possible.

Rosina’s honest approach and passion helped keep me engaged until the very end is why I will continue to recommend her to all.

Rosina Aston gave me a great Leaning Experience

If you always wanted to complete a qualification to acknowledge what you are capable of, Rosina Aston is the “trainer” for you.

Thank you Rosina, without your support, encouragement and direction I am confident I would not have achieved my Diploma. You were always there to put me on the right path, to support and guide me with my studies.

Your depth of knowledge, enthusiasm and your coaching greatly assisted me in obtaining my work goals.
I have great respect for Rosina and highly recommend her to anyone who wants to extend their career.

Donna Worger – KKCT Pty Ltd


Her content knowledge of business management and leadership mixed with her training expertise and passion for the success of her students made training with Rosina an absolute pleasure.

Rosina offered support and guidance around the clock and always provided prompt, meaningful responses and feedback when help was sought.

I can’t speak highly enough of the training experience that Rosina and the NIEX team provides.

Drew O’Brien, Acting Contracts Inspector, Urban Amenity Branch, Field Services – Brisbane City Council


Coming to the end of my Degree, studying full time and working, I realised the career direction I wanted to take. I enrolled with Rosina for the Certificate IV in Work Health and Safety. As you can imagine having a full time study load at university whilst working and doing my Certificate on top of this things were chaotic.

Studying with NIEX and under the guidance and support of Rosina, I was able to really flex my available time and her willingness to support my learning 24 hrs. a day, 7 days a week was what enabled me to succeed and push through the content of the course, whilst still being able to fully absorb all the information.

I can honestly say that the mentoring and educational experience I had whilst studying through NIEX and under Rosina’s guidance was the most enjoyable, fulfilling and immersive one I have ever had. I now feel confident with my skills and knowledge due to her teaching and support and I would do all of my future learning through Rosina.
