TGA are committed to providing a website that is accessible to the widest possible audience, including those with sight, audio and motor impairment restrictions.
We now offer a high contrast, text only version of the website for users who wish to view a graphically low, content only version of the site. High Contrast heightens the diversity between the text and background colour of this site, making it more distinct. This reduces eyestrain and increases readability for many people. Use the Toggle high contrast button at the top right hand side of the site header to activate this feature.
