SELF-ADHESIVEAlso in the issue Snowy Mountain Scheme:
Stamp Snowy Mountains Scheme- Tailwater Tunnel it reflects the thematic directions:
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two portals common at each end, though there may be access and ventilation openings at various points along the length. A pipeline is not a tunnel,though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.
