I thought I'd add some more information, with photos, since I have noticed that watercolour sticks are now more readily available, including in Australia :-)
Here is my collection of watercolour sticks after my trip to the US last year. Some I have cut down to add colours to my students' palettes, some to add to my own palettes. I guess you could use them straight from the stick and not put them in a palette at all but that certainly isn't my suggestion. Once there is only 1/5 left of a stick I press it into a half pan, and, of course, write on the side what colour it is in a permanent pen.

The only disadvantage is that you can't make up custom colours with them.
Note, though they were designed to draw with, I don't choose to use them for drawing. This is in part because I prefer to work with pencils and pens, but it is also because I live in a humid climate and I find they go soft so are not suitable for drawing where I live.
You don't need all of those yellows - I'd suggest hansa yellow light and hansa yellow deep (or you might prefer hansa yellow medium and quinacridone gold.)
Here's the set of 14 painted out, including three of the yellows, three reds, three blues and some lovely earth colours. Sodalite genuine is a dark blue pigment that is very similar to my Jane's Grey. I scribbled on the paler with the sticks and brushed water over them, though in the palette you would just touch a wet brush to them as with other watercolour pans.

And here are some of the gorgeous extras.
Serpentine genuine is normally an expensive colour in a tube but all the sticks are priced the same. I love it for grassy meadows.
Undersea green is a wonderful olive green that works beautifully in Australia as it perfectly captures our dull gum leaves. It can be a distant green too, watered down for atmospheric effects.
Sap green works the world over as a convenient realistic foliage green - add more light yellow to brighten it up further.
Piemontite genuine is an earthy red. Really lovely with yellow ochre and cerulean chromium as an earth triad. Indian red has more colour but isn't available as a stick.
Burnt umber is a colour that I like to have as a pair with raw umber (also not available as a stick). It isn't an essential colour since you can create this hue by mixing a little ultramarine with the burnt sienna, but it can be useful to have convenient darks.
An finally an 18-colour palette option.
Happy travels :-)
