In Australia anyone can call themselves a nutritionist. There is no register, no minimum qualification and nothing stopping a person who finished a weekend course from using the title on a business card.
Dietitian is different, and the distinction that actually matters is a credential rather than a word.
The credential to look for
The one to check is Accredited Practising Dietitian, usually shortened to APD. It is administered by Dietitians Australia, it requires an accredited university degree in dietetics, and holding it means the person is bound by a professional code and has to complete ongoing training to keep it.
For sports specifically there is a second credential, Accredited Sports Dietitian, administered by Sports Dietitians Australia. That one sits on top of the APD and requires additional postgraduate study and supervised experience with athletes.
So the useful question when you are choosing someone is not "are you a dietitian or a nutritionist". It is "are you an APD, and can I check". Both organisations run public directories, and it takes about a minute.
Where this actually bites
Two places.
Rebates and referrals are the first. Medicare referral pathways for allied health, and most private health extras cover for dietetics, are generally tied to the APD credential. The specifics change from year to year and vary by fund, so speak to your GP and ring your fund before you assume, but a practitioner without the credential will usually mean you pay the full fee with nothing back.
Scope is the second, and it is the more important one. Dietetics training covers medical nutrition therapy, which means working with people who have a diagnosed condition alongside their nutrition goal. Diabetes, coeliac disease, kidney disease, disordered eating, gastrointestinal conditions, pregnancy. A good nutritionist may be excellent at general healthy eating advice and completely out of their depth with any of those, and the risk is that neither of you realises it until something goes wrong.
Where a nutritionist can be a good choice
Plenty of nutritionists are well qualified. Many hold a three year Bachelor of Nutrition Science, which is a real degree with real content, and some work in public health, food industry or research roles where dietetics training is not the relevant background.
If you want general education about food, meal ideas, or help building basic habits, and you have no medical history in play, a qualified nutritionist may suit you perfectly well and often costs less. Ask what they studied and where. The answer will tell you quickly.
The sports layer
For athletes there is a further split that gets missed. An APD who works mainly in clinical nutrition is a very good clinician and may not have spent much time on carbohydrate periodisation, fight camp planning, or fuelling a fifteen year old through a growth spurt and three trainings a week.
That is the gap Accredited Sports Dietitian exists to fill. It matters most in the situations where the nutrition question is inseparable from the sport: making weight in a division without wrecking the camp, managing low energy availability, or feeding a junior athlete through adolescence. Our writing on sports nutrition for young athletes and on structured weight loss for female combat athletes is the sort of thing that credential covers.
Questions worth asking before you book
Are you an Accredited Practising Dietitian, and what is your registration number. Do you hold Accredited Sports Dietitian as well. Have you worked with my sport, or my condition, before. Can I claim this on my private health. What happens between appointments.
Any practitioner worth seeing will answer all five without hesitating.
What we are
Strive Performance Dietetics is a team of Accredited Practising Dietitians in Alexandria, several of whom also hold Accredited Sports Dietitian. We do one to one consultations, DEXA and RMR testing in the same clinic, and work with everyone from world title fighters to people who just want to eat better and stop guessing.
If you want to start with the principles rather than an appointment, the Essentials of Sports Nutrition guide covers the fundamentals, and our dietitian's guide to healthy weight loss is a good place to begin if weight is the goal.
